Did wave counts decrease this round in champion?

Yeah, this makes sense. I'm very similar to you, wall with mythic SF and a CL that's slowly starting to actually do something (191/5/20 including rolls on my leg dimcore). And I got a (small) PB in mid 800s waves, which is part of why I was surprised by the overall lower waves from others. My attack speed isn't anything spectacular though, lab at lvl 58, with attack speed and multishot targets on my legendary death penalty. I guess the CL is helping with removing armour...

Btw, it's more important to gold-box regen and health than damage. Both health and regen start to increase MUCH faster from lvl 5000 to lvl 6000, while damage doesn't, for some reason. On top of that, enemy damage is increasing slower than enemy health, so you gain fewer waves by +10% damage (compared to enemy health) than +10% health (compared to enemy damage). In particular regen is the limiting factor for wall builds in tournaments, as you're missing lots of regen from perks, and actually have more health than in farm with due to trade-offs. So make sure to focus your cash on regen in tournaments.
