Efficiencies

I believe their numbers, but that means that the efficiencies for these gearboxes are pretty darn good.

After doing some calculations, I get these efficiencies:

Gearbox in High: 92%
Gearbox in Low: 97.5%

The "old" gearboxes had these efficiencies:

Old Gearbox in High: 80%
Old Gearbox in Low: 70%

... so...

With a larger motor, more efficient gearboxes, and a bigger circuit breakers (40A compared to 30A), these drill motors may be close to double the power compared to last year's Bosch motor/gearbox combination. Holy torque, Batman!
