Yes, I agree, that this kind of tournament requires a tremendous amount of time. And it amazes me, that @browery finds the time to do it with #poliac. This is why I suggested it to Actifit team. Because they would be capable to pull the date from the blockchain about average activity, and also could create tickets on marketplace for AFIT tokens (that might spur some trading on hive engine).
This could be monthly event. Champions could be crowned and dethroned :D
