Isn't the date of the testing important?I would suspect that eventually, the various labs adopt the newest nomenclature and standards for the various markers as these standards are established, and therefore, at some point the conversions would no longer be necessary for those who are tested after the newer standards are adopted.I believe this has been the case for certain markers tested by certain labs over the past several years, as compared to more recent results which have already taken into account the changes in standards.Newer standards are adopted for different markers at different time, and as the marker standards have been upgraded by each lab, then depending on when testing was done, conversions may be necessary for some markers and not for others. For nearly every conversion chart I have seen, the date the new standards were adopted by each individual laboratory for a particular marker is not stated. Most of my results are from October 2007, but I've also had some advanced marker testing done as recently as this month.I am at a complete loss with regards to which values need to be converted, if any. The confusion over this issue interferes with any possible search for Y-DNA matches, as a failure to make the conversions by either myself, or by those who "should" be genetic matches to me, would fail to identify potential matches, while wrongfully offering others as potential matches. Has anyone come up with any suggestions on how this conversion process could be done on a more reliable and accurate basis on each of the websites where Y-DNA results are voluntarily posted? Perhaps each website should have a location where the testing date for each marker tested can be entered so that automatic conversion of results could be done?As I see it, as it stands right now, the results being posted become virtually meaningless if no one knows which of their results need to be converted, and which results have already been adjusted by the lab due to adoption of the newer standards.
