If you look at the BG blitz ladders, you’ll see that it’s really only highly inflated for the top top players. It’s only the top 40 or so players of a spec that are really inflated in Blitz when compared to RSS. In fact, Once outside of the top 200 in Blitz, you’re actually deflated in comparison to those outside the top 200 in RSS.
2s deflation is probably the worst, being 2200+ literally puts you in the top 100 players in the country.
3s deflation is pretty bad as well. The old school cutoff for glad (top .5%) is currently only 2300.
Blitz is also deflated, it’s just the top 30-40 players making it “appear” inflated. The rest of the players on the blitz ladder are struggling.
