from Chris Boyle of Sportsnet,

Rebound shots, like deflections, occur almost exclusively in the home plate area. Although the success rate is lower than clean shots, it is higher than transition or deflection opportunities. In future studies I will isolate the success rate on rebound shots if a goaltender is square to the puck in contrast to when a re-adjustment must take place through a butterfly transition.

These early results do indicate that there is an undermined pool of data below the surface of the current research. There is a reason that even-strength save percentage is favoured over straight save percentage by the #fancystat community—it’s because shorthanded teams give up more high-quality opportunities of this nature.
