Technically yes but from an engineering point of view no . What you are measuring is , uncocked , the firing pin at rest . What. the firing pin does when it flies forward is to go past the rest point and go until it hits the stop point i.e the point of no further travel .
So if you have a problem of not firing a round due to not igniting the primer the first port of call should be the round itself i.e headspace/primer seating / primer hardness etc. Then look to the bolt i.e clean it first & then polish the firing pin and internals , and then as a very last resort mess with the firing pin travel/protrusion.As an example someone ,who will remain anonymous, cocked up a calibre conversion to the point the chamber was about 0.010" to long . My solution in the end was to polish the firing pin / bolt internals to decrease lock time and increase firing pin protrusion( which is not straight forward) and now it works
