I missed this part:

I'll go back and redo it later, here are my results without modifying scores.

Rank using the 2016 system had about 80% correlation with OPR and a WLT system in 2016 would have only had about 73% correlation with OPR.

However, it should be noted that, if the ranking system were WLT, teams would have behaved differently, and it is probably safe to assume that the correlation of WLT with OPR would have increased. It is questionable though if it would have increased to 80+%.

I have attached a bunch of graphs comparing different things at Palmetto, comparing ranking score against OPR value produced the strongest correlation, so I took that comparison and applied it to 8 other events. Those results are also attached.
