Probably so. It really depends on if their setup can calibrate in under 5 minutes. If you have a permanent or semi-permanent setup then just save the calibration data in PHD2 and make sure you have your mount connected via ASCOM to PHD2. PHD2 will scale the dec guiding for different declination, it will also detect side of pier and between PHD2 and SGP get your mount flipped.
I have an obs (that sees little use 
) but when I do run it I just load up the PHD2 calibration data and I'm off and guiding. This does assume that things don't change in your setup. So if you're using an OAG and rotate or you move your guider around then you need to manually recalibrate.
Where did you edit this setting and save it? There are 2 levels of "saving" things in SGP:
- Profile - Think of this like a template. You edit these from the Equipment Profile accessible through the Tools menu.
- Sequence - You can use a profile to create a sequence, but you don't have to. A sequence stores targets as well as frame info (profiles have neither). You can edit a sequence from the control panel.
If you open up SGP you may or may not be using a sequence or a profile. It really depends on how you have things setup. But if you use and save a sequence then when you open that sequence back up your settings should be saved. Including backlash.
