The problem is getting average goaltending is hard to do in an actual gameThe issue is using sv% as an indicator of average goaltending on a game by game basis, you can get a shutout with average goaltending or you can get blown out, sv% really only works as an indicator when the sample is large enough.
Even then, as JD1 pointed out, remove one bad goal and an average .900sv% becomes a .933sv%, if you try to argue only games with a sv% of .900 +/- .01 is average goaltending, only 9 games all season qualify, a guy like Skinner with pretty average sv% on the season would only have 4 average games out of 54.
So what is average in this context? The standard deviation league wide of a games sv% is .06, so anything from .966 to .841 would fall into that. Even at half a standard deviation you'd get Vezina caliber sv% of .935 all the way down to league worst of .872.
Here's Korpisalo's games in which he got credited with a decision;
Korpisalo Sv% Range W L OTL
1 std Dev .841-.967 15 14 4 --- 85 pts pace
1/2 std Dev .873-.935 10 8 3 --- 90 pts pace
1/4 std Dev .888-.920 9 4 1 --- 111 pts pace
1/8 std Dev .896-.912 4 1 0 --- 131 pts pace
Outside 1 std dev >.967, <.841 4 7 0 --- 60 pts pace
So what's average goaltending? Take your pick, but the .900 - .910 range you alluded to earlier is a pretty damn narrow definition, and the closer we get to average, the more our win % climbs.
Take a 30 shot game.
The only scenario where your goaltending is average is 27 saves. 28 or more is great. 26 or less sucks.
Take a 40 shot game.
The only scenario where you're goaltender is average is 36 saves. 37 or more is great. 35 or less sucks.
So, what does that mean? It means "average" goaltending in a single game doesn't happen all that often.
So @jbeck5 to say "we only win when we get great goaltending" of course we do. That's pretty normal. If we get lousy goaltending i.e. 26 saves in a 30 shot game, then the other side has to get REALLY lousy goaltending for us to win.
A little better than average goaltending might see you get 6 out of 10 games with 28 saves or better and 4 out of 10 with 26 saves or worse. But at 28 and 26 saves in 6 and 4 games respectively, that's 272 saves in 300. That's.907. A little above average and probably no worse than a 5-4-1 w/l record in a 10 game segment. Do it again and get a little better record and you have a 6-4 10 game segment. Extrapolate that out and you've got a 94 season.
It'd be quite hard to lose any of the games where you get the 28 save performance and hard to win any of the games where you get the 26 save performances
