70 mmr is an inflation difference of…13 weeks at the current rate. What are you talking about? That is a MASSIVE difference in what mmr is at. And this guess came in, with a MMR guess that is roughly…26 weeks off at the high end.
Why do you think MMR inflation is “simply a matter of people queuing”. That is literally not what inflation is. Inflation strictly is the artificial increase in rating that is put into the system. More people queuing, is not a inflation mechanism, it is simply how ELO systems work.
