The SNP test is what definitively defines the haplogroup. Various
algorithms have been developed which attempt to predict the haplogroup
based on the Y-STR haplotype results. Sometimes the prediction is fuzzy
and it points to more than one haplogroup as close and thus possible.
The SNP test you ordered will clear things up. Plus as more people get
SNP tested, the predictor algorithms based on the associated haplotypes
for the various haplogroups will get better.
Hope this helps.
