Why did I have this win rate if the matchmaking is rigged?

This effectively proves that standard matchmaking by winrate will clump paper rock and scissors into like groups over time, such that as you climb in ranks, you’ll tend to face favorable matchups, then even matchups, then unfavorable matchups, then (if you can break through the Counter Wall) favorable matchups again, at which point the cycle repeats.

He then said this proved matchmaking wasn’t random, also a true statement. Rigged arguments say that, so do matchmaking arguments. Then the thread devolved into the usual “it’s rigged” “no it’s not!”.
