Using FTDNA frequencies for groups like V13 will lead to underestimation, as many V13s on FTDNA are only tested up to M35, and so not counted in the V13 frequency for a country. For M35 FTDNA gives a frequency of 6% in France, which is reliable and is an upper limit for V13. I think it's reasonable that V13 will be ~4% and other E-M35 ~2%. Given that E-M35 apart from V13 is mostly found outside of Europe, it's also likely nearly all arrived in France during the Roman era.
