Not at all, that is exactly how the shift assist is designed to work and I find that the more the transmission is loaded the better it changes
For maximum acceleration I just nail the throttle and snick up just before the red line in each gear, the shifter blips the throttle for you
The electronics stop it wheelying too so you can be as untalented as you like
Exactly. GSAP is meant to be used with an open throttle, ideally at high revs. I don't think this RTZ chap has any experience of GSAP.
