Katago supports score estimation, which is often a much more human-understandable metric than the winrate. Ie. a bot will think a 5 point lead is 99%+ while for a human it’s much less of a guarantee. Seeing that the game was within a 5 point margin instead would be useful. Similarly if you’re ahead by a lot, the winrate is unaffected by blunders while they would show up in the score estimate.
Or, in an even game a half point mistake can be a 90% blunder.
I’d assume that this would be a fairly reasonable change or addition.
