Fun with PDO

I put together a massive undocumented stats sheet that, if you go through the pain of figuring it out before I document it, will let you look at individual and on-ice shooting and shot quality. One simple but interesting result at 5-on-5:

Stdev Stdev
Observed Shot Quality % Shot Quality
On-Ice Shot% 0.789 0.267 11.4
On-Ice Save% 0.607 0.201 10.9
PDO 0.898 0.307 11.7

That jives with previous estimates of the impact of shot quality. But don't take my word for it - you have all the data you need to prove it and to figure out, at the margins, where shot quality matters. I hope we can move on to the other 89% of what drives goal-scoring and goal-prevention.
