i had seen in an esc control race with a limited gear ratio, the local sponsored driver was running the same esc than some invited driver. the invited driver was being passed significantly in the main straight for several runs of battery. and he just publicly asked why his "thing" is so slow,....and everyone had the same query.
after that, the local guy changed to another one from the pool of control esc, then he was no way following the invited driver.
that was not a "H" brand,....
