Point being that if not from a dig, it's pretty much a driver's race around a track assuming you know how to rev-match in an MT.
I guess it depends on the track and the gear ratios. A buddy of mine had a 2011 ZCP 6MT with suspension, pulley and tune at a time when my car was still stock. We were on the exact same wheels and tires (Enkei NT03 and Nitto NT01). On the back straight of LCMT (80-135mph), on more than one occasion, I was able to pull a clean pass on him. The only other difference was 6MT vs DCT.
