I watched some of that replay, and it looks pretty damning to me. I didn't see even one time a hint of a blip with upshifts, and looking at the MPR data, by 11 minutes into the race, EE3's clutch slip had fallen back to the initial, pre-start level – and it stayed there for the entire rest of the race – while others were already by that time around amounts I think correspond to around 10%-20%. (edit: just to clarify, EE3 only took in clutch slip at the start, after which the slip started to fall down like it does on a stationary car doing nothing at all...)
With a car like XFG (or any car for that matter) and autoclutch, that doesn't seem to be humanly possible – not even remotely.
