Spring loaded connectors rely heavily on the projected and calculated spring force of each connector after primary polishing to ensure firm mating inside the split sleeve of the adapters. If a connector was over polished (in excess of 3 times from beginning) for example, repeatable reading in both insertion loss and return loss will be difficult to control.   Most notable will be the return loss which will be exhibit much more variation in readings because of the variation on spring force.

There is no documented number of times a connector can be re-polished published that I am aware of but typically I instruct all new manufacturers to limit the number of  re-polishing to 2 times. This is to prevent excess removal of the ceramic ferrule material and subsequent shortening of the ferrule from the tip to the base of the metal flange.
