you will still be accelerating as long as you engage clutch and lift of throttle at exactly the same time, if not you will be in engine braking once off throttle until the clutch is down. you defo are acelerating as ive looked at my speedo a few times when changing from 3rd to 4th and i engage clutch at 95 and its over 100 once im in 4th so im either still accelerating or my speedo cant keep up
