does constantly dashing make you do less damage?

Hello there, Kalista mains o/

I'm new to Kalista, and something has been bugging me recently - I've noticed in the mid-late game my autoattack speed is noticeably higher when I just stand still and autoattack, instead of dashing around. I suspect it's because dashing animation in between AA, but I don't know for sure - maybe I'm just dashing wrong or something. Testing it in practice tool, I see a drop of ~10% in dps, if not more.

Is this normal? Should I use dashing just for kiting / dodging skillshots, and if I can stand still, do so?
