Heads up -- Shot Quality only tracking shots on goal, not shot attempts
This may be a known issue with the shot quality stats that were just added, but looking through some CSVs with the new data, it appears as though only shots on goal are counted, which means the penalty applied to blocked shots is not factored in.
To illustrate this: I'm looking at a game where the home team had 29 shots on goal. Their quality numbers are 10-8-8-3-0. But the away team players have been credited with 7 blocked shots, which means the quality stat is looking only at shots the goalie saved, rather than all shot attempts.
I'm not sure if this is intentional, but I'm guessing the intent is to record shots on goal and shots that *could* have been on goal, but never reached the net to find out, as opposed to all shot attempts (since a missed shot could never be a goal).
Just wanted to point it out! Thanks again for adding more advanced stats guys! I'm super excited to mess around with them. Can't wait for shot quality to start showing up in player stats.
