If what you say is true...
The total effeciency (power out / power in) for:
1 - 2w/(14v * .221A) = 64.6%
2 - 3w/(14v * .323A) = 66.3%
The rig is more effecient with the drive set to max. I don't know how the
parts would feel about that...

My parents tell me that I just take up time and space. It's true - I'm into relativity theory.
