Are these based on average within vigintiles? I was thinking I was just exceptionally (relatively) good at big cubes, then I realized my official results reflect that, so if it was calculated the way I’d understood the Min for 4/5/6 should be lower.
Using my official results I come in at:
2x2/3x3: 0.409
3x3/4x4: 3.55
4x4/5x5: 1.62
5x5/6x6: 1.80
6x6/7x7: 1.50
My at-home global average is slightly better than that for 4x4 (3.30) but slightly worse for everything else. I haven’t checked other events.
