The formula
PP efficiency = power play goals ÷ opportunities × 100. PK rate = penalties killed without a goal against ÷ penalties taken × 100
At the individual level, useful tracking is simple: log shifts on the power play and penalty kill (RinkLog has Power play and Penalty kill buttons during shifts), then look at what share of production comes from those situations. A player scoring half their points on the power play has a very different profile from a 5-on-5 scorer, and both profiles have value.
RinkLog measures and computes all of this automatically during your hockey, ball hockey and ringette games.
