Ideally you want PHD to calibrate in about 20 to 30 steps in each direction
too few and the guiding doesnt seem to hold as well; too many-well more than 60 PHD gives up; between 30 and 60-its a long time for you to be sitting there waiting for it to do its thing
you control the number of steps by setting the duration of the calibration steps.
very much depends on the scope and also on where you are pointed. Closer to the pole, longer calibration steps-1000ms or more
far from the pole 500 ms may be enough
you dont want it to finish calibration in say 4 or 5 steps which can happen if you have too large a calibration step
