She also protected herself and Senya from the worst effects of a hyperdrive explosion, which should be roughly comparable to Revan tanking the Temple of Sacrifice's super weapon.
She has also telekinetically ripped apart starships and generators, and slaughtered dozens of Knights of Zakuul. As well as having the power to instantly crush Senya's skull with the Force and Senya dmitted to being defenseless against it.
All of those feats are chained Vaylin.

She has done nothing even remotely on Revan's level while chained, IIRC.
Tearing apart a skyscraper sized object, being able to completely bypass Senya's Force defenses with the disparity in power between them and slaughtering dozens of Knights and bringing down ships by unknown means along with what should logically be a substantial power growth up to KOTET should put unchained Vaylin at least approaching Revan's level.
