from Stephen Burtch of Sportsnet,

First, we account for the league-wide spread in shot attempt differentials in each game state – rarer game states will show a wider spread in results. We then determine a weighted average for every NHL player’s percentage of shot attempts, weighting their results in different situations by the amount of TOI they have played at 5v5 in each game score state (trailing by 2+, trailing by 1, tied, leading by 1, leading by 2+).

The resulting statistic, Z-Score Adjusted Fenwick For Percentage (Z-Score Adj. FF%), gives us a reasonable tool for comparing the results of individual NHL skaters relatively early in the season. When we combine this with individual skater PDO (Sum of On-Ice SH% and SV% at 5v5) we can form a clearer picture of who is driving the successes and failures around the NHL so far this season.

Some of the more interesting highlights for Z-Score Adjusted FF% so far would be as follows:
