There are some nice tools for this, if anyone really wants to know.

It must be more.  I have put in at least 10 man years too, so 20 is
quite a bare minimum.

Considering that we both claim 10my and you have double the commits I
have, other questions arise: Possibly you put in 13my and I only 7my,
and if 10 for us both a good estimate, then how do our relative
average productivity quota compute?

The next step is even more interesting; kloc counting only goes so far;
on one project that I've been very productive in, I have put in minus
150,000 loc in 1.5 years, adding lots of functionality and
process/product infrastructure: adding continuous build, splitting the
tests into microtests and a regression test suite, monitoring test
coverage, etc.
