In PHD2 it is recommended to calibrate near the meridian with dec=0 and then re-use that calibration for guiding when slewing toward the imaging target for the night. 
When using the Ekos internal guider does the same principle applies for calibration? So far I have been doing my calibration on my target for the night and recalibrate every time i move to a new target...
I'm just wondering if my guiding accuracy would improve by calibrating near the meridian with dec at zero.
