how to view accurate statistics on games in percentage terms?

I need help with the question. How to look at the exact statistics in percentage terms regarding wins, losses, draws, namely, the number of games won by checkmate, withdrawal of the opponent, surrender of the opponent. Same with losing. And also, the number of draws by agreement, stalemate.
I will be very grateful for your help.

That's not something available in Stats. Insights for Diamond has them.

I recall that I used to be able to see what percentage of games are won by checkmate, timeout, etc., and also the percentage of games are drawn by repetition or agreement. What ever happened to that feature?

There used to be a small selection of game result stats for each pool, though it didn't include all termination types. I'm not completely sure why that was removed but my understanding is stays will be getting a complete overhaul at some point.
