The thing about top20 rankings is, it only considers the Big events, aka, Tier-1 and at best Tier-1.5 performance. s1mple underperforms/doesn't care about CIS, due to exactly this. It's not important in HLTV Top20 rankings anyway. And in fact, if you take out his CIS performance, his stats would be much higher than right now. That's because his ratings against CIS teams are 1.14, 1.16, and so on, while against the Tier1 teams, his rating is much higher. His entire 2020 rating dropped from 1.30 to 1.28 in just one tournament - IEM NY CIS, because Navi didn't care after securing major "legends" status.
