i went from a 2400 gram wheelset to a 4800 gram wheelset with double the inertia and it shows about 0.07 second advantage for the lighter wheels to ~20mph with a power curve peaking a 750 watts and average of 400 watts
if you did the same weight increase without any intertia increase (as if it were just frame weight) it saves 0.044 seconds
so .016 seconds difference for a sprint from 0 to ~20, wheel weight vs frame weight in this case.
im not getting the negative speed you are
