I am not sold on the study either, but I did expect a bit of a bump in calls against when playing in Montreal based on the aforementioned eye test. Clearly that's not the case. Perhaps the study would have been better served using penalty minutes rather than total calls, and it should factor in the timing of calls (causing 5 on 3's for example, or 4-4's nullifying the other teams PP). There are lots of subtle ways to make the penalties count "more" to make up the amount of penalties called.
Ok, removing my foil hat.
