Here in Mid-Missouri, near Columbia, I can get USALS to go from 33w to 148 easy... Had to use 1.2 to go from 33w to get to 30w.
Make sure your lat/long settings are all set up correctly, and that you've tweaked to get the arc in as good as you can... sometimes if ends of the arc are off, it has to do with the motor not tracking right, sometimes that can be due to pole not being plumb.
