Didn't really see a change in performance with my single V56 (figured I'd just throw it in for testing's sake) as performance went up by 0.2% (well within margin of error). However, I really like what you've done with the wealth of features (in particular, the restart function if it drops below a hash threshold) and the UX/UI looks relatively aesthetic compared to other miners I've used.

Definitely a project to be proud of and something I'd gladly pay the 0.65% fee for.
