Microstepping high detent steppers

Hi Group,
I seem to recall a very brief comment about microstepping accuracy with high detent steppers but cannot locate anything in the archives.
I assume the positional accuracy of microsteps is innaccurate with high detent motors. But are those positional inaccuracies repeatable for the precisely same coordinates of the tool cutting path?
List wisdom seems to generally be that reducing stepper current below the maximum rated motor current has certain advantages.
Am I correct in believing that if one were microstepping a high detent motor then reduced motor current would enable the motors inherent detent force to become more influential on a particular microstep position than it would be if the motor had the maximum rated current flowing through its coils?
Regards
Bob Thomas
