Only if I'm using flexible filaments do i drop down to 20-30mm/s.
That said I haven't done much with pet-g yet.

I think for something like a mumu I'd probably accept 50mm/s - anything much lower than that and even small multi material prints are going to take an enormously long time.
50mm/s is what I use mostly. Default Prusa profiles use 60mm/s for inner perimeters, 15mm/s for outer. I haven't really felt the need to bump up the speeds, although I think there's some room for every machine I have. PrusaSlicer has some 100mm/s profiles, might try them some time to see if the speedup is worth it.

PETG might have some limitations about speed, if I recall correctly I read somewhere that it might even fail to print properly after certain speed. I have printed some at 60mm/s as PrusaSlicer slices it and it turned out fine.
