I like that line combinations are given minute totals for ES lines and % for special teams as seen here:
I would recommend changing the abbreviation from IT (presumably "ice time") to TOI ("time on ice"), which is the standard abbreviation for the statistic in the NHL, or more accurately for this game tactic situation, TOI/G.
A few of us were also wondering whether or not there's going to be a way to adjust length of individual shifts. It's common for players to play shorter shifts later in the game as they get more fatigued, and I was curious if this would be included.
