There is something odd then about our ASD or variance estimations from the
respective databases we use. I find Western (old) I1b having substantially
smaller ASD than (old) I1b2 --- more than a factor of 2 difference. There
are four separate clades of (old) I1b --- Dinaric, Western, M26+, and Isles.
I wonder if you have Isles mixed in with one of the three you indicate?
Isles is smallest in SMGF but should be greater fraction if one uses Ysearch
in which Dinaric is suppressed.

I have Western having .54 of the variance of ANgloSaxon I1a, while M26+ is
1.2 the variance. Dinaric has .64 the variance. I did not have enough
Isles to bother with a variance.

What's your "age" for AngloSaxon I1a, or all of I1a if you did it as a
whole?
