He didn't have an answer.
Optimum acceleration occurs at maximum HP, not at maximum torque nor minimum BSFC, which the CVT is tuned to operate at.

And, since HP is a combined function of how often torque is being produced, it (HP) is simultaneously a rising function of RPM and a falling function of torque (which "peaks" between 2/3-3/4 of engine max HP RPM), ie: HP increases so long as torque is increasing, but decreases as soon as torque begins to stop increasing:

HP = (T*RPM)/5,252
