I will go on record that I don't race my SRT6 or accelerate WOT very rarely, so midrange has been working fine.
I won't comment on your last statement, as it's heresy.
WRT to the mileage, it's largely due to the higher energy density base stock. The formulation of race gas is completely different than the pump variety.
