Of course the TMRCA for an existing clade can not be in future.
The wide confidence intervals tell us one thing with surety: we need
lots more STRs with the right characteristics if we want more precise
As it stands, you can get more precision if you don't mind being less
accurate. And vice versa. But I think most of us would agree that
precision without accuracy is 100% useless, while accuracy without
precision is less than 100% useless.
