If someone will prepare such a parsed out S21 database, they can run it
through Generations2 and see what happens, or if sent to me I will do it.

That's the reason I have been saying the interclade age estimates are really
more worth investing time in finding. The interclade age between S21 or
parsed S21 against S116+ ought not change much. Remember, that latter
interclade age estimate closer to 4000 years provides a bound on how old the
separate S21 and S116 MRCAs can be.
