Since the Surname studies are so new, as in the Y-DNA science,
we can only use an overall mutation rate of .002 for each marker at each birth.

We know the markers do mutate are different rates
There is not enough data to do a full analysis of the mutation rate.
My guess is that there are about 25,000 Y-DNA test done with 12 markers (or
so) world wide
and about half of those are expanded to more marker.
To get the mutation rate one needs the genealogy - which is what we are
doing for science.
It may be several years before we have enough data to do good analysis.

Your report is the first I have seen from a Lab that gave any clue as to
fast and slow
This is good information. Thank you for reporting that here.
Eventually we (all) will have better statistics for each marker
