The Y-HAP test is clearly not intended to be a free Deep Clade test, much
less an Advanced SNP suite. Its purpose seems to be to satisfy the most
common level of customer curiosity about deep ancestry.

The confidence percentage claim was calculated from an experiment in which
one week of new haplogroup predictions (about 300) were subjected to SNP
Assurance. Only one prediction was proven wrong. Hence, someone might
claim that the prediction algorithm offers 99.7% confidence.
