Hello,
I need help in understanding just how a match is defined. I had a 25
marker test done by FTDNA and was told that I matched another individual
at the high resolution level with a two-step mutation. Comparing their
results and mine I find we differ at five loci by a allele value of one
in each case. Those loci are and the corresponding values are:

DYSMineHis
390 2425
459a 8 9
464a 15 16
464b 1617
464c 1617
464d 17 18

To me this looks a match of 20/25 with 5 one step mutations. Can someone
say why not?
