Default Rotor gap to distributor body terminals

I was curious as to how critical is the gap between the rotor and the distributor body terminals?

I purchased a replacement rotor and distributor body and after checking the clearance's for the gap which in Les Andrews mechanics handbook states .025", I found mine to be in the area of approx. .012" with a feeler gauge. This is a repro unit.

What effect does this have on the overall preformance, when you are setting the timing, and the preformance of the engine?
Do you typically need to file down the rotor contact to achieve this clearance?

Thanks to all in advance for your reply's.
