You think the BM was that much of a boost?
The text makes it pretty clear it was.
"It had been many years since Farfalla had fought while empowered by Worror's battle meditation. He had forgotten how much quicker and stronger the Ithorian's amazing talent made him feel. The Force flowed through him with greater power, filling him with its might."
"Then he, too, leapt to the side to avoid being crushed, surviving only because his reflexes were heightened by Worror's power."
"Fueled by Worror's battle meditation, she switched styles seamlessly, and her arms and blades became a blur as they carved figure eights in the air to catch and absorb the bolts of dark side energy."
With it, she was coming across as a lot faster than Bane
Not really. She landed as many blows as she did not because she was much faster, but because Bane had no need to defend those areas of his body due to the protection provided by the Orbalisks.
(who is possessive of perhaps the best speed feats we've ever seen in the mythos).
Heh, nah.
I wouldn't assume that she's anything but top tier in speed while unamped,
Even when amped, Sidious is certainly faster than she.
and skill wise I'd say she probably has them all beat.
Not much suggests this. She's probably close, though.
