So unless you assume that calibrating the motor's zero position is part of the alignment, then USALS doesn't always work.
I *THINK* that with most motors, that you can calibrate the zero position just by manually setting it to zero and doing a hard reset. I've never bothered doing that on mine, because I was afraid that it would change all my diseqC-1.2 positions, but I think it would work.

I do consider part of the alignment process is making sure the motor is set to zero. besides it makes the rest of the setup a lot easier once you get zeroed in on your true south sat the rest just fall in to place. I am not saying usals is better just easier to align the dish.
