This will hopefully put some rest to the nonsense.
Ok Columbia is the RPI 150 as for WarrenNolan.
In order to calculate what Memphis’ rpi would be after a win vs. 150RPI (and remember the premise was a 10+ point jump in a LO replacement game) we need to get Memphis AWP and Opp w % and opp-opp win %.
Memphis’ current AWP is .7530. After the home win, it goes up to .7609. Hold onto that.
We then have to figure out Columbia’s new metrics. Their AWP will drop (after the loss) from .6667 to .6400. Their opp win % (by virtue of playing Memphis) will go up from .4584 to .4743.
Ok, now we look at Memphis’ 50% OWP category. Columbia’s .6400 will serve as 1/20th (number of games now played) of that stat. The previous rating was .5748 (based upon combined SOS, but that will suffice) times 19 (games played) is 10.9212. Add that to .6400 to get 11.5612 and then divide by 20 to get the new 50% OWP of .5781.
Finally, to get the 25% OOWP, we take the .5748, again multiply by 19 to get 10.9212. Add .4743 to that (Columbia’s OWP) to get 11.3955. Divided by 20, it is .5698.
Alright.
We now have the three numbers:
Memphis AWP: .7530.
Memphis OWP: .5781
Memphis OOWP: .5698.
Since the OWP is weighed twice, we will add the .7530 + (2*.5781) + .5698 to get 2.4790. Divided by four, that is .6198.
So, previous to this, Memphis RPI was .6193.
The new RPI of .6198 does NOT even advance Memphis one spot in the RPI.
22. New Mexico 0.6226
23. Saint Louis 0.6199
24. Memphis 0.6198
25 Colorado 0.6191
This should once and for all put to rest the premise set forth in the OP.
