My first 22.00 and this closes a gap for 21.33 to 25.67 that i had. After analysis i feel much better about the mean, i think 22 21 20 are reasonable here, and i could've had 22 22 20 from my drs, and i only missed 22 on a1 cause of time management and on a2 it's quite tricky so that's not too bad, really funny a3. I was really tired when we started the solves and i had a headache for most of the mean so i'm happy with this performance, only missing 1.00 from human findable
