I'll admit that I'm not completely sure what's interesting about this data - I have it for every goaltender and every shooter - so if you've got a good idea, send it my way.
Update: Hockey Numbers was all over this back in 2007. The 2006-07 data is no longer available, oddly enough.

Take a look at the shot chart here:

If you float over a shot, it'll show you where it was directed at the goalie.

It would be interesting to learn from your analysis the following:
1) how many left handed goalies according to your statistics? I know there are only 3 left handed starters in NHL.
2) How many left and right handed goalies have better Sv% on the glove side than on the blocker side (zone 1 and 2)?
3) What is the average number of shots per game in the zone 1 and 2 with respect to the knowledge which Sv% is higher?
I can keep going with my questions :)
Thank you

1) There were 15 right-catching goalies or so. I can't remember how many shots they saw, but it was a not-insignificant percentage of the league total. I'll check.
2) Small sample size, one year's worth of shots per goalie...Not sure we can draw a conclusion.
3) Again, I'll check.

2)Among those from above how many have Glove Sv% > Blocker Sv%? According to your total results right handed goalies have Glove Sv% > Blocker Sv% (seems logical), however left-handed goalies have an opposite situation. Is that right???

2) The data appears to show that right-handed catching goalies get beat glove side more than blocker side, but that there's no difference for left-catchers. This may be due to most players being left-handed shots...Or having too few right-handed catchers. But I wouldn't draw too many conclusions.

Among the 26 lefties who faced 200+ high shots, the average difference in shooting percentage between high left and high right was 0.18% (to the left, but it's meaningless.) 13 goalies were above and 13 were below.
I don't really find this information all that exciting - if you'd like the raw data, I'll email it to you.

I think the key split is high vs. low. Because of the large difference in expected save percentage between a high shot and a low shot, I'd probably be more interested in the frequency of high shots against goalies than their individual save percentages. That would give us more of sense of who is facing more difficult shots.
Unfortunately, it looks to me like there are some reporting issues with the data, a lot of variance from rink to rink.

I know they record as they go, then go back and rationalize it with the NHL.com data after the fact.
I watched as they came up for an Oiler game once, and the guy doing it here must have been high. I doubt he was within 10 feet of the shot loaction most of the time. There was a shot that hit the goalie in the mask and it counted as a pad save. The whole thing was a complete mess.
So ignore Edmonton's data. Or check along as a game is played and see if he's gotten any better.
