Yep. Because of the OT, the +/- for 40 minutes will be a bit less.
I left off two since they didn't play in the last game and weren't in its season stats:
Papadaki 24.8
Green 37.3
If I add up the total +/- for all players (1758) and divide by the total minutes (2225)
and then multiply by 40, I get 31.60.
When I look at the games, I calculate 940-586 = 354 points for 11.125 40-minut games
354/11.125 = 31.82 per 40 minutes. (.125 for the 5 minute overtime)
The numbers SHOULD agree. See below for details. GI,GO.
They also have Eff there, so you can see how Eff gives higher numbers for the posts & forwards and lower numbers to guards, compared to +/-.
Ratios of Eff / +/-
Lepolo 0.387
Brink 1.164
Jones 0.761
Jump 0.496
Iriafen 1.033
Emma-Nnopu 0.400
Belibi 1.456
Prechtel 0.846
Nivar 0.365
Bosgana 0.750
Demetre 0.513
Harriel 0.424
Betts 1.631
Note that what I show above is the ratio of Eff divided by +/-, not the ratio of two players' Eff nor +/-.
For instance, Brink show an Eff of 241 and a +/- of 207 while Betts had an Eff of 137 and +/- of 84.
So, by Eff, Betts's contributions have been 57% of Brink, but Betts's +/- has only been 40.6% of Brink.
The fact that Betts 1.631 above is bigger than Brink's 1.164 means that what she does when in the
game contributes more to EFF versus the score difference than what Brink does.

Details:
The +/- for all the players must be wrong. It should total to 354*5 = 1770 rather than 1758.
The recorded +/- is low by 12.
Where I find the +/- for each game and season:
Go to the
Stanford page at StatBroadcast, find the latest WBB game and click on Final Stats.
Then click on Home (or Visitor) Stats, and then on Season. Last column is +/-
The
FGCU game has bad +/-. The total for the players is 117. It should be (93-69)*5 = 120. +/- low by 3
The
Grambling game has bad +/-. The total for the players is 183. It should be (87-50)*5 = 185. +/- low by 2
The Hawaii game has bad +/-. The total for the players is 147. It should be 145. +/- high by 2.
I can understand why this error happens. The scorekeeper fails to show the 5 players in the game. Perhaps 4 players or 6 players get credit for the scoring during some interval.
Those errors doesn't explain it all. So I looked deeper.
In the
first game, Demetre had +/- of 11; in the
2nd, she had 32. But it the season stats for game 2, her total +/- was listed as 42, not 43.
Wow. Isn't this why you have computers? All those stats are in the same system, but the addition is wrong???
It turns out that the site doesn't have the Pacific game. I had to work backwards from the season numbers after the Portland game.
Likewise, the game's Plus/Minus wasn't in the Gonzaga results, so I used the differences between the seasons stats from that game versus the previous game.
None of the games in Hawaii had a season +/- column, so the next chance to check their addition is the Santa Clara game.
Oh, wow. Lots of errors. (Here, high means the season total was higher than the sum of the individual games)
Lepolo, Brink, Jones, Jump were short by 2. Iriafen was 12 too low. Nivar was 4 too low.
Bosgana was 8 too high. Demetre was 14 too high. Harriel was 5 too high.
(Maybe it wasn't an addition error. Maybe they started from a separately kept record of Plus/Minus provided by Stanford.)
