THis is almost certainly not necessary, and a probably a waste of time. If you are tracking from 30 to 129, and every satellite is off in the same direction, and can be corrected by running the motor a few clicks, then you are NOT out of alignment, and making changes to the alignment will not help, and may make things worse. What is described here is a case of just being out of sync, ie the alignment of the mount is OK, and the dish is following the arc, but the motor is just mixed up with respect to where it is along the arc.
In theory, USALS shouldn't get out of sync, however the motor itself can be out of sync. Ie if it doesn't know where it's zero position is, then when you tell it to go to zero, it will be at the wrong point in the arc, and when you tell it to go to any point in the arc, it will be off. My motor is off by about 2 degrees, when you tell it to go to zero.
I would really recommend just changing the home longitude setting in the receiver as mentioned above, and then seeing if USALS will take the dish to the sats reliably. If it does, then I'd leave it at that. It is also possible, that you can check to see if the goto-zero command takes the dish to it's zero position (go out to dish and see if it is centered). If not, manually move the dish to it's zero position, and do a hard reset to the motor. This might (I haven't tried this, because I have already stored all my sat positions in the diseqC 1.2 system, and use that, so I'm not positive that this will work) function like a resync command.
If one of the above still doesn't solve the problem, then yes, you might go through all the fine tuning steps, if it is even possible from your location, although my tendency would just be to start over and do the 2 step alignment right in the first place rather than the 30 step alignment.
But really, if you are tracking from 30 to 129, your dish is aligned OK, and I really wouldn't mess with it, unless you enjoy tinkering.
But that's just my opinion.

And once again we disagree. My logic is simple. As you move either east or west the dish not only points in that direction it also climbs in either a positive or negative value along with skew of the lnbf. This is not a big dish So as your dish needs to be actually pointing either lower or higher and to the left of where it is stopping but skew is correct where you stopped optimum signal would be achieved following the path I layed out.

There really is no reason to "Kentucky Windage" the settings. Another potential problem that had not occured to me previously is the mast being tilted 2 degrees or so to the west. That would be where I would look first.
