That's not what I said and its seems to miss the point. I agree that Tie breaks are best applied to players that are tied.
It makes no difference which player it is calculated for. That Performance calculation relies on ratings to be effective, and is flawed when player ratings are not reliable, as is common at a CYCC.
This is going around in circles and I don't think we disagree. The point of this excercise is that you can use the formula you like best.
