Street Fighter 6 uses two systems. League Points are a “keep them playing” type, and Master Rate is pretty much pure Elo.
Everyone starts with LP only and initial placement matches put you into a league with progressively fewer guard rails as you live higher. Rookie league can’t lose LP at all, there’s a win streak bonus up to gold, and you can’t demote to a lower league until platinum. Throughout it all there’s very slight upward pressure on LP, you get slightly more more a win then you lose for a loss.
Finally you reach the topmost league, Master, the final guard rails fall away and you’re given 1500MR to join in the net zero Elo ranking pool. You basically need to demonstrate that you have a willingness to keep playing before they will use that style of matchmaking. “Real” skill based ranking effectively begins there, with the lower ranks being made more to show dedication rather than just ability.
They’re absolutely being disingenuous, but I think it’s important to keep in mind that the purpose of debate is not generally to change the mind of the person you’re debating with. It’s intended to be done with an audience (or judges in a formal competitive debate), and it’s the audience that you’re trying to sway to your side.
