I’ve noticed some discussion recently about the 4 ranks each player has and how they do / don’t interact. I’ve also seen discussed questions about, say, a 14kyu player who has never played, say, any correspondence games, and so while their other 3 ranks may be ~14 their corr rank is 25.
As a thought, what if all 4 ranks started with the Provosional “?” after them, and that temporary rank only goes away after 5 ranked games in each format?
