Looking at some numbers, it seems the highest % of a certain pop tend to be associated to phasing, when results generally* increase in resolution. In my list of 12, for example, the highest Italian % (47.4), Balkan (7.6), Iberian (4.9), British (8.3), Scandinavian (0.8) and Eastern E. (1.7) are from people who had close relatives tested too.
*I say "generally" because after phasing one of the mentioned matches had her S.E. dropped off 0.2, NW.E. dropped off 3.6 and Broadly European increased 3.6 in the speculative mode, oddly. I presume the precision estimated by 23andMe (see Testing & Validation in https://www.23andme.com/ancestry-composition-guide/) refers to the conservative threashold, otherwise, those results couldn't have changed that way, in theory (precision of 0.95 for NW.E.). However, I haven't recorded her sub-regional results before phasing, then I don't know if these results, particularly, increased in resolution or not. Possibly they did.
He told me he has more samples right now, however, the averages haven't changed significantly since the first (those I posted) have been done months ago.

I'm sure one is there: himself, heheh. I think at least two of my matches are there, but let's wait. I just asked him.This is great! I have added the percentages. Maybe I should combine your results of Veneto with those from the pie chart? Do you know if your results are already included?
