By points/30d, you're somewhere in the top 10% of active Warzone accounts (https://docs.google.com/spreadsheets/d/e/2PACX-1vQyTPMiILDNWvPRKg5eVriTTMsIqTpIskaTLqRy71ylXLP-9m1OHabmy3OG6tzBTxZh6luSjH0aIP2D/pubchart?oid=350570762&format=interactive
). So I'd expect your ongoing game count to be even higher-percentile, since many active accounts don't play MD games. If you're playing 30 serious games where you take 1 turn every 2 days (since usually players do back-to-back turns) and each turn takes 5 minutes, then you spend 1h-1h30m on Warzone every day just handling those MD games. I'd say that's extremely high compared to the active playerbase but unexceptional for the superplayers who make up the sort of formalized community.
As for me, I'm in 2 MD games. I prefer 0 and can't really handle 5 (mostly because I play my games seriously, so time-per-turn on MDs can get pretty high; on a no-stakes 2v2 for some coin tourney, we took 2 weeks on picks against mediocre opponents). When I feel particularly active, I go up to around 10-15. When I was super active I had about 20-25 at a time, with a peak of about 100 (TLW takeover, playing every player to introduce the new management). I think I also had like 30-40 at a time ongoing when I was onboarding players into Optimum, but those games took very low time-per-turn (SE1W against weak players) and even then weren't sustainable.
local deployment GoT are fun but incredibly time-consuming when you get to a certain point, if anything is gonna make me buy membership those are.
