Totally agree that YSR overvalues blowouts. If you really need it, you can get around this by applying the YSR algorithm but excluding all mismatches.YSR is HIGHLY inaccurate when it comes to older teams (14 yo +) .... this is because it rewards blowouts way too much so if you play regularly vs weak opponents in league you are ranked way higher than you should be..... this is 100 percent true for the girls teams so I am assuming the same for the boys as it is the same algorithm but my son no longer plays (baseball full time) so can't say for sure for boys teams
However, if you just want a quick sanity check on the strength of CSL gold versus elite academy, do you have a better idea than average YSR score?
