Two things we have found: Jabbing while staggered when you're not getting hit by jab (but you are getting hit by something else, like hslash at hslash corners) does not cause knockback, and if you have overdrive and move 3 into an oncoming lunge, you suffer no knockback
The replay has those instances, as well as a bunch of playing around with manipulating efficacy to avoid knockback and seeing what works and what doesn't
