I have no interest in speaking for or against statistics but your parting shot brings back a couple of memories.
Back in the days when I lived with a BF and a PVR, he groused a couple of times about how shots are counted. (Yeah, I know, but he was an accountant. Still is.) Pretending to be interested, I sat with paper and pen and he replayed the first period of a few games and we counted the actual shots on the goalie. Didn't tally with the 'official number'. Sometimes the discrepancy was enough that we had to go back and repeat the counting (yeah, accountant) and confirm the recorded number was off by as many as 2 or 3 shots.
When I see all these TOI and %SV and WTF and whatever, I wonder if they're just as "pliable".
