Augmented Polyhymnia And Multi-step SCs

Helooo everyone!

I was wondering, has anyone maxed the augments on Polyhymnia yet?

Judging by other one-handed weapons, the Accuracy is likely +50, but the sTP and the WSDmg is still unknown. They could be anything between +5% to +10% for max augments. (Edit: Augments are ACC+50, sTP+8, WSD+5)

A Sari with any augments will beat that DPS-wise... However, I am wondering if Polyhymnia may be worth making for situational uses like multi-stepping.

Has anyone done any multi-step WS testing with Polyhymnia? Could the +10 regain and +8 sTP make it possible to self 6-step for Vagary?
