Round 2: Mace starts at the strongest he gets to in RotS

Spoiler:

Sidious.

While Anakin may be >Yoda, the gap isn't large enough to overcome sheev. Make this KFV and there's a chance

Sheev.

Sheev, though it would be a fantastic fight.

Sheev BBQs them.

What statements do we have that suggest Sheev's growth in power up to ROTJ was so vast that he could go from an extremely difficult fight with Mace, to beating Windu and Anakin at once?

Team. ROTJ > ROTS but there's no evidence the growth was massive, only that there was some.
