I'm not participating in this tournament but I think you should rethink the mappool of the knockoutstage for the next time. I've just tried 3 of the maps of the knockout stage pool and i couldn't pass any of them on first try(2 from the HR pool+Dopamine). Chances are high that these maps will become a mashfest and the winner will be who is best at flailing when I at 30k can't pass these maps comfortably. Also becomes evident when looking at the (semi-)finals with loads of scores below 90% and fails. The difference between groupphase and knockoutstage is massive and easily spans a whole star of difficulty range. You're also not staying true to your announcement of the upper limit of 4.5 stars: You put a 4.54 star map into the HR-pool which makes it 4.83 stars and there are also other deviations. You might also want to consider that close to none at or above 50k can read AR10 so you might want to search some maps around AR6.5 for the groupphase-HR-pool.
