@AroHar What do you mean by "giving the desired one for yourself"?
Perhaps you are thinking of the exact same scheme I thought of. Picture this -- I make a new account, where I play rated games using Houdini 6 against the LeelaChess bot. I play several games like this, crushing Leela until I reach, say, 2800 elo. Then, I use that account to challenge my yabbadabbadooooo account to a rated game, and I lose on purpose to myself a few dozen times.
Now, I've boosted myself several hundred elo points, and it shows that I've beaten a 2800 in my Top 5 Best Wins list. Isn't that brilliant?
