No, the bonuses did that. They operate contrary to their intended purpose, which is why "Erik Honsel is a beast." He's exploiting the mathematics of an inefficient system. Fortunately, this year was an outlier, chalk cruised in the first two rounds, and he got hosed., But people picking like him are likely to win way more times than not for as long as the current bonus system is in place.You just made filling out a bracket not fun.
I sure hope you don't stop. I enjoy the pool for what it is. I fill out a single bracket, based on my own subjective (and often uninformed) belief of who will actually win each game, and harbor no illusion of ever winning. I bet on the actual games for my gambling fix, and follow my picks in the pool for funsies.He's probably correct and he reminds me why I say I am done running this.
Okay, this is enough to get me--an almost-never-posting lurker--to chime in!He's probably correct and he reminds me why I say I am done running this.
I hope I'm not overstating the case. When I say it's beatable, I mean it in the gambling context. That is, it's possible to get a distinct edge, which over a long enough time horizon will generate positive value. In simple and inaccurate terms, if picking the games by hunch, randomly, or some other system would give you a 1 in 300 chance of winning, and this system moves it down to 1 in 30, that is a massive exploitable edge.Okay, this is enough to get me--an almost-never-posting lurker--to chime in!
Dan, this is by far my favorite pool and I would be so sad to see it go!
The Needler is making good points about EV of these early round games, but he's overstating the case a bit. Choosing every 12 and 13 to win is a great way to be on top of the standings right now, but can have diminishing returns as the tournament progresses, as you have automatically eliminated viable contenders from reaching the later rounds where the point totals for wins can more than make up for the upset-points in the first round.
The most important factor in winning this pool is picking the correct finals matchup and the correct champion (that's how I won this pool two years ago), which I think most people would agree is as it should be. Getting those early round upsets is a great tie-breaker, and I think it's great that The Needler is pointing out some good math to consider for those who like to take a more measured approach to bracket-filling, but I think it's important to point out that that kind of strategy isn't going to outright win the tournament--it still comes down to picking the right finalists.
This is a great discussion, and these are great points. Specific to the 11s and 12s. the 6s and 5s you are picking against wouldn't even be favored to win in the second round, so there is very little harm in picking against them aside from losing out on the 1 point - but the 1 point is so inconsequential to the bonus you pick up by nailing an 11 or a 12. And similarly in the second round, you only get 2 points for picking a 4 over a 5/12 or a 3 over a 6/11; but if you nail a 12 over a 4 or an 11 over a 3 that's equal to picking up an extra 4 second round wins. With only 16 second round games, just hitting on 1 of these probably makes it worthwhile. Then you take your regular chalk from there on forward, and yes, you have to get the final four (mostly) right and pick the champion, but like you said there is so much bunching of those picks that the differentiator will be the upset bonuses. But if everyone starts adopting the "pick all 9-12 seeds" strategy, then we might get into a situation where we come down to the tiebreak - which would be a truly ridiculous way to determine this thing, IMO.I hope I'm not overstating the case. When I say it's beatable, I mean it in the gambling context. That is, it's possible to get a distinct edge, which over a long enough time horizon will generate positive value.

You are of course correct that the most points are gained by correctly predicting the winner and finalist. The problem is, there is tremendous bunching among those picks, such that unless you have amassed a large number of points in the early rounds, you're going to lose, even if you correctly pick the winner, unless that pick is a huge upset.
This scoring system values two things over all the others - correctly picking large upsets (which happen almost exclusively in the first two rounds), and correctly picking the winner and finalist. So, while you can't win the tournament in the first two rounds, you can almost certainly lose it there. And the way people do so, in each and every year, is by missing the upsets. When correctly picking a 12-seed to win in the first round is equal to correctly picking EIGHT favorites or an Elite 8 winner, it's pretty obvious what matters is not missing an upset. The reason you won the pool two years ago (Congrats!) is not because you picked #1-seed UNC; I'm sure there were at least a couple dozen others who did so. I'd be willing to bet it's because you had Xavier, Rhode Island, Middle Tennessee State, and USC in the first round.
Also, your diminishing returns point, while superficially persuasive, is not borne out by the statistics. Picking the 11 and 12s to win their first two games only eliminates 3, 4, (each around 10%) 5, and 6 (each around 3%) seeds, who advance to the Final Four extremely rarely. Attempting to correctly pick those rare occurrences is, longterm, an overwhelmingly losing strategy, ie much worse than piicking the 11s and 12s to go through to the Sweet 16.
Also, I'm just noticing - you are a perfect example! You did an exemplary job picking winners over the first two rounds. 87% correct, better than the leaders at 85%. Yet because you didn't pick the upsets, you're already 22 points behind, tied for 61st place, and I would guess with very little chance of winning, since there are 35 other players who've picked UVA, including two who are already at least 15 points ahead of you.Okay, this is enough to get me--an almost-never-posting lurker--to chime in!
But with the bonus structure it absolutely isn't a statistically better bet. Take the 8/9 for example - that is statistically as close to a coin flip as you'll ever get. These games are very often pick-ems in Vegas. Yet the 9 gets 2 point if they win, and the 8 gets 1.Another way to think about it: I think most people understand that, if you just went game by game and picked the statistically more likely winner via a reputable source like KenPom or 538, you will have submitted a bracket that is statistically more likely to perform well. Most people don't do that, however, because they find it fun to try and correctly pick games subjectively, and the statistical advantage to doing otherwise often gets washed out in the variance of a 1-tournament sample size each year. It was even mentioned above that if you remove the bonus points, people wouldn't just pick chalk because of course it never pays out as straight chalk. But that doesn't mean it isn't actually statistically a better bet to do that.
Well, but people have unlimited entries. I would say an extremely strong strategy would be to complete 8 brackets; in each of them, you piick the 9-12 seeds in the first round, and the 11 and 12s in the second. Otherwise straight chalk, picking each of the 1-seeds in one bracket, and each of the 2-seeds in another.I'll defer to your point about diminishing returns; it was not the correct term for me to use. It's more that there is a non-negligible opportunity cost, and while your EV will be higher if you pick all those upsets, the sample size of 1 tournament each year, plus the (nearly) zero-sum prize structure makes other methods of selection viable contenders. Not sure if I'm making sense.
Right--sorry, I was unclear. In this sense I was speaking about NCAA brackets more broadly, not necessarily ones with Murphy's bonus points structure.But with the bonus structure it absolutely isn't a statistically better bet.

But this isn't true for a bonus points set-up. In a non-bonus points pool, if you just picked the statistically most likely to win team in each matchup, you would never, ever win the pool, because there are always upsets - you have to pick upsets in order to differentiate yourself.Right--sorry, I was unclear. In this sense I was speaking about NCAA brackets more broadly, not necessarily ones with Murphy's bonus points structure.
My meta-point was just that I think people already have a broad understanding that there are statistical best practices in selecting a bracket that they feel comfortable ignoring in the context of a high-variance, winner-takes-all, contest, maybe because they think they can outsmart the stats, or maybe because they just think its more fun that way.
And to be clear, you are right about every single thing you've posted (including my own chances this year, haha!). I chimed in not to debunk you, but because people seemed discouraged by your points to the point of suggesting altering or disbanding the pool, which I would not like to see.
Yeah, I'm sure there are some people who understand the significant mathematical built-in advantages available and still pick contrary to those. As I've said, I'm one. But I would guess the vast majority don't. I think if everybody really understood or internalized say that by picking every 12-seed you could never lose more than 4 points to the field in the first round, and could gain as many as 32, or that by picking a #8 seed over a #9 you're essentially saying the 8 is twice as likely to win, you'd see very, very different brackets than the ones actually filled out.But this isn't true for a bonus points set-up.

Whereas in a bonus points pool, picking upsets becomes almost formulaic because picking a bunch of games correctly in the first round is less important than the bonus points. You absolutely COULD win the tournament with a formulaic approach.
This post alone just internalized it for me. I'm taking all 9-12 next year, at least in the first round.Yeah, I'm sure there are some people who understand the significant mathematical built-in advantages available and still pick contrary to those.

For what it's worth, even in this year of nearly-unprecedented 2nd round chalk, each bracket using this system would have 88 points, and of course all Elite 8 teams still alive.Well, but people have unlimited entries.

I'd be willing to do some backtesting if I could get the scoring leaders from past pools, but I'd guess in the great majority of years, this would place at least 1 or 2 brackets very close to the top.
Should be up within the next 30 minutes.At what point do the scenarios go live again?
I don't understand how "worst finish points" is nearly always higher than "current points." If somebody picks every game incorrectly going forward, those numbers should be the same, no?Should be up within the next 30 minutes.
Yeah that doesn’t make sense. I’ll check with them on that.I don't understand how "worst finish points" is nearly always higher than "current points." If somebody picks every game incorrectly going forward, those numbers should be the same, no?
Yeah, I’m sure it’s a hassle, and it is appreciated. You should add a small administration fee. 50 cents or a dollar for each entry shouldn’t be objectionable to people.I guess I know this isn’t the best way to score the pool. But It’s been the format for so long it would tough to change. It will something I will I think about for next year.
I will say if it wasn’t for finding Venmo I very much doubt I would still be running this. The year PayPal froze my account I really was ready to say that’s it. Another issue coming up is the software I use and they also host the pool is saying they’re not sure how much longer they will be offering it. I’m sure there are others but I’m not looking forward to that.
I received an answer. Supposedly in the one that says what's the worst finish place it gives what's the worst position you'll wind up in. And worst finish points tells you how many points you will have if you finish in that place.I don't understand how "worst finish points" is nearly always higher than "current points."

Yeah, that still doesn't make any sense to me, though I'm not sure it matters.I received an answer.

By my calculations under this system, you'd now have all 8 brackets with 108 (picking the 11 and 12s two win two games), or 118 (picking them to lose in the second round) points. In 5 of your 8 brackets you'd still have the champion alive, and a potential to score as many as 218 points total (if MSU beats UVA or Kentucky beats Duke or Gonzaga in the final).For what it's worth, even in this year of nearly-unprecedented 2nd round chalk, each bracket using this system would have 88 points, and of course all Elite 8 teams still alive.
If you chose not to have the 11s and 12s win in the second round and went with the #3 and #4 chalk instead, you'd have 98 points with all 8 brackets tied for 5th, 14 Sweet 16 teams, every Elite 8 team all 8 potential champions still alive.
