I don't think steals figure into PER. Not much defensively does.
Steals and blocks are factored in, but damn -- that formula is straight-up out of control!
How do you find out BRoy's PER for tonight!!!!!!!!
ROY +23
SERGIO +21
GREG +20
per NBA.com
Formula for PER: http://en.wikipedia.org/wiki/Player_Efficiency_Rating
You're right, I don't see blocks or steals mentioned. I don't really want to take the time to figure out and apply the formula. But if I get drunk later and don't have a girl around I might figure it out.

PER is a bear to figure because it's based on OTHER values that are nearly constantly shifting (VOP, League Pace, Team Pace, League FT makes per foul, etc.).

Plugging in numbers from last night, Roy finished with 27 (categorized by Hollinger as "Probable Player of the Game", a step down from "Probably the best performance in the league that night" and a step up from "A very strong effort", which is where Oden was at 19.5.
50+: An historic performance
40-49.9: One of the best games of the entire season
30-39.9: Probably the best performance in the league that night
20-29.9: Probable Player of the Game selection
15-19.9: A very strong effort
12-14.9: Reasonably solid performance
8-11.9: Average
5-7.9: Subpar game of didn't see many minutes

This is a similar good minus bad calculation to EFF - only with weighting factors for specific stats he considers more/less important. It's just a coincidence that both Roy's EFF and and Game Score worked out to 27 last night. Here's the EFF and Game Scores for Roy's top four games this season:
12/18 EFF = 49 Game Score = 43.7
12/12 EFF = 37 Game Score = 31.3
12/27 EFF = 35 Game Score = 29.2
12/16 EFF = 34 Game Score = 29.4
So, according to the Games Scores metric, Roy's 52-point game was likely "One of the best games of the entire season" and he's had three others that are borderline (slightly above or slightly below) "Probably the best performance in the league that night".
