Its resistance is listed as 0.0006 ohms.
Voltage drop = current * resistance, let's assume it's operating at its max 45amp capacity.
Vdrop = 0.0006 * 45 = 0.027 volts
At my club, we charge 2S batteries to 8.4 volts.
0.027 / 8.4 = 0.3%.
So let's say a very expensive ESC can deploy twice the FETs to lower resistance by half.
We'd be talking about a 0.15% improvement.
I seriously don't think human perception feel changes that small. And even if it theoretically does improve lap times, surely there are better ways to chase laptimes per dollar?
I do agree that when people can not drive the same fast laptimes over and over again they do not have to take care of these very minor improvements but most do believe in them. But for people on the top these small things can make a difference to get on podiom or not.
And there comes the stupidity of more than 90% of the drivers thinking that they can buy laptimes to get to the top while getting close to the top is for 99% with the skils of driving and the setup of the car.
