Well, since I did the histograms for DYS388 and DYS392, I'm posting them
below. From my database of 2337 Y-DNA J haplotypes. It is these
histograms that lead me to conclude DYS388 is mutating faster than
DYS392 in Y-DNA haplogroup J/J1/J2. I'm looking forward to seeing your
results.

As an aside one notices the curious "bumps" in the data for J-(xJ2)~ J1
for both DYS388=13 and DYS392=13 due to subclades. Bonnie, in her FTDNA
Y-DNA J Project, is showing subclades with these too.
