I don't know too much about overall percentages -- at least not with the
algorithm 23andme uses. For example, I have a proven 2nd cousin once removed
and our overall match is 1.76% and her son (my 3rd cousin) matches 1.02%
total DNA according to 23andme. However, our match is through The cousins'
paternal side and my maternal side. Where we match most closely is our X
chromosomes and this stands to reason -- since the son only inherited a single
X (and it came from his mother which is our matching side--through the
mother's father on back), the match is with the X I inherited from my
father--the line we share. We have half identical matches for more than 90% of the X
chromosome and only one other fairly large matching segment on chromosome
2.

Now, the "theoretical" amount of DNA one shares with a 1/2 first cousin

6.25%. But in the "real world" the actual percentage could be as much as
a
point or two higher or lower.
