wow, that looks pretty good. How did you keep your voltages so flat? Did you let off the throttle if it got around 2.8v or did it never get to that point? I'm using probably twice as much current on my controller as you so maybe that's the difference. Actually, I do remember that my batteries only sag to about 3.05v under 20 amps so maybe if you only use 1C, it looks like that.

Were you flooring the throttle the whole time? What would happen if you floored the throttle for say 15 minutes straight? or have you tried that?
