OK I see you are saying I've used the different generation ages at the
wrong point.

But if you have included generation age (25) in the mutation rate will
not the mutation rate change if ages of 30 or 33 are used to calculate
mutation rate? And won't the margin of error also change with changes to
the mutation rate? Then the generation age used will affect the number
of generations and the time to the common ancestor. Too short a
generation = too young an age.
