I'm not familiar wit hthe phasing tool but I'm already on gedmatch so looking forward to it!
Before the Ancestry DNA reboot, my results here were rather disappointing but with a raw data upload to gedmatch, I got results that made much more sense though props to the reboot because they really make sense in light of the family I can confirm.
I used the chrome browser extension for the first time a week ago and it showed up some interesting results but I'll really need my parents results to make more sense of them.
The chrome browser extension tool, once I downloaded the results to excel and parsed the data for unique surnames in unique tree administrators, showed several hundred "Parsons" but only 20 or so Edwards (Edwards being my surname, my Father being a suspected NPE, and Parsons being a name I just don't freaking recognize).
