We have received results for 3 Kazakh G1a1-L1324, which have common ancestor lived about 600 years ago, according to oral genealogy. Their STRs are very close to each other and form very distinctive cluster.
Shared novel variants vary from 299 to 306 and novel variants found in one and not found in another person vary from 20 to 38 High confidence SNPs.
I have met here different mutation rates which state that 1 mutation occur every 150 years, in average. Is my understanding correct that 20 non-shared SNPs equal to 20x150=3000 years? This number - 3000 years between close relatives, doesn't make any sense to me.

Try to think to what I support from many years, that the calculation of the MRCA based upon the STR mutation rate has no meaning and the usual calculation should be multiplied for 2.5 to 3 or more. This is another proof that I was right.
