You might be interested in a report by Dr. Bruce Walsh on the Family
Tree DNA website. One point made there is that there is a law of
diminishing returns as the number of markers tested increases.

I believe the original article is

Walsh, Bruce , 2001. Estimating the time to the MRCA for the Y
chromosome or mtDNA for a pair of individuals, Genetics 158: 897--912

I'm not sure it the whole article is available but you might try
searching pubmed.
