Maybe you should learn to read (and get a hold of the context) before responding to something trying to act all tough and mighty.
Notably, my last paragraph, where I specifically mention that more might go uncalled than during the regular season due to higher stakes and thus higher intensity.
I responded to a post where the OP mentioned the number of PP opportunities going down in the playoffs, not to a post that said the reffing standard was different.
Nice to see said analysis, which I didn't bother going to go into details with due to lack of readily available data on my end (would have taken one-two hours at least to colligate all of it over a large enough sample), has already been made. In the end, the initial claim does remain a "myth", but it wouldn't if the claim was "the number of PP opportunities goes down the further you go in the playoffs", albeit as stated, the sample is very small and thus provides with a large interval of confidence (that might actually be larger than the observed reduction of ~7%) if looking at averages.
It'd be interesting to see the analysis pushed even further in order to really explain if the observed data is a result of reffing or rather other external factors, such as :
1) Teams may take lesser risks the higher the stakes are (almost impossible to do with data)
2) Better teams tend to take less penalties, and better teams tend to go farther in the playoffs;
3) Teams adapt to how referees call the games (also almost impossible to do with data, or even at all)
4) As playoffs goes on, players get more and more tired, and thus they might be less likely to draw/take some types of penalties (skating slower, hitting less hard, etc.)
etc.
