... I know this thread died out over a week ago, but I have a bit of a minor issue with the arithmetic used to determine Gretzky's 88-89 R-ON and R-OFF numbers. Being a Kings' fan, I was messing around with their 88-89 numbers out of curiosity, and everything was matching up perfectly (with a minor/insignificant difference in the bit players) - except for Gretzky's and Nicholls' numbers.
Gretzky was on the ice for 213 total goals, and 72 PP goals. The difference is 141.
The SH goals for is estimated as (PPGA/TmPPGA)*TmSHGF. So, (43/80)*22 = 11.825.
So, Gretzky's F-ON is 141-11.825, which is 129.175, which rounds off to 129.2.
Gretzky was on the ice for 169 total goals against, and 43 PP goals against. The difference is 126.
The SH goals against is estimated as (PPGF/TmPPGF)*TmSHGA. So, (72/82)*13 = 11.414.
So, Gretzky's A-ON is 126-11.414, which is 114.586, which rounds off to 114.6.
The Kings scored 294 non-PP goals, and 22 shorthanded goals. The difference is 272.
The Kings allowed 255 non-PP goals, and 13 shorthanded goals. The difference is 242.
Gretzky's F-OFF is 272-129.2, which is 142.8. Gretzky's A-OFF is 242-114.6, which is 127.4.
The R-ON ratio for Gretzky is 129.2/114.6, which is 1.127, and that rounds off to 1.13.
The R-OFF ratio for Gretzky is 142.8/127.4, which is 1.12.
So, Gretzky's ratio was 1.13 on, 1.12 off ... not 1.10 on, 1.15 off. The R-NET should be 1.01, not 0.96.
With Nicholls, (and I'll just shorthand this one) his estimated SH goals for is 10.45, estimated SH goals against is 9.988. So 194-63-10.45=120.55, rounding to 120.6, and 139-38-9.988=91.012, rounding to 91.0.
Nicholls' F-OFF is 272-120.6=151.4. Nicholls' A-OFF is 242-91.0=151.0.
Nicholls' R-ON is 120.6/91.0, which is 1.32. Nicholls' R-OFF is 151.4/151.0, which is 1.00.
So, Nicholls' ratio is 1.32 on, 1.00 off ... not 1.29 on, 1.03 off. The R-NET should be 1.32, not 1.25.
Now, Overpass - if there are numbers regarding Gretz and Bernie that I'm not aware of, let me know. Or, check me on this? It's just a minor adjustment, but it's more of a matter of wanting to have correctness more than anything.
