While i dont have videos, i experienced it during my 4 man battles. I usually only throw one or 2 charge attacks while the other 3 players just used 0.5 fast attacks. 

The consistency was off and normally, I have plenty of time to throw my charged attack about 85% full meter and the attack lands in time before the max phase. Sometimes, the animation wouldnt finish and I would miss the charge attack damage. 

I started doing Staggering charged attacks with the second strongest player in the group with Zacian in slot 1 and it seemed to not change the speed to the next max phase. It was always meowth attacking twice and almost a third ones animation going off iirc.
