I'm glad that helps. Of course the default, Average, should work as
well, and it does in as much as the calculations are correct, but due
to a lack of rounding, and the method that gnucash stores fractions,
we get an overflow situation. I'll be patching that soon.

We believe that the IRR is the "best" measure of return, because it allows any two investments to be meaningfully compared..  The calculation is non-trivial.  I recommend "Financial Calculation Programs for Linux" by James Shapiro at http://www.linuxjournal.com/article/2545.  He gives C, Java, and Perl programs for calculating IRR.

Thanks for the links.

great! I'm glad it's working for you. 

The additional information, income and realized gain, are longer term
projects and I can't make any reasonable guess when, or even if, they
will be done. But I'll put them on the list ;)
