Why "Rank Demotion" Shouldn't Really Exist

Doublelift, a famous Leage of legends streamer and ex-pro, confirmed on his stream that Lol ranked used at least three different sorting algoritms for the ranked matchmaking:

1) normal, which prioritized players with no ELO vs rank irregularities to be matched with each other

2) "recovery", which prioritized players that once had a much higher ELO than his current rank to be matched with each other

3) smurfs, which prioritized players that obviously was playing on smurf accounts to be matched with each other

Just speculations but perhaps is Apex using something similar.  Perhaps are players that previously reached platinum matched together regardless of what rank they currently play in beween bronze and gold. This would validate the bronze-to-gold lobbies from a competitive fairness pov and also explain why bronze-gold lobbies are even sweatier than some platinum lobbies....

Guess this is easily examined by creating a brand-new account and purposely play badly, like just hipfire spray and go <1 KD.. If you play like this through the entire Rookie and bronze ranks and still get very bad opponent in Silver, than I think its safe to say that there in fact are several rank queues. Perhaps I will do this by playing with controller as a M+K player. I will legit be a <1 KD player then =)
