Not convinced. Peak power is certainly the place of max speed, I would

I did the math earlier. Peak power is at higher revs, so you can use a
lower gear. This means that the torque at the output of the gearbox is
higher at peak torque.

Like this:

2000 RPM, 400nM, geared down 2:1 to 1000 RPM gives you 400nM.
5000 RPM, 200nM, geared down 5:1 to 1000 RPM gives you 1000nM.

Dave refuses to admit that this means you get better acceleration at
peak power than at peak torque.

The only exception is when you are in 1st gear and cannot change down.
