This is not the same setup as the above graphs. It's my Slash 4x4 1415 with a SV2 Pro,

I added a cap and bec, radared at 45mph. Also I wasn't near as consistent with the driving on the 5, you can see the 0 had more steady runtime. So if you take out the down time, it had a higher average. I also did not run the same battery in each, but they are matching packs, I'm gonna switch them around, and try to be more consistent.
5* timing
0*
Temps were within a few degees of each other, and the 5* felt better. Pulled a few wheelies with it, couldn't on the 0.
