What do you reckon?
Physics. If your 22s weigh the same as 20s, but the weight is concentrated farther away from the axis, it takes more torque to turn them. If they weigh less, it could take the same or less power to turn them.

It takes more power to swing a 4 foot pole with a 10 lbs weight on the end than it does to swing a 6 foot pole with a 10lbs weight on the end.
