I see I gave an incomplete explanation - The fund data is maintained in 
a spreadsheet, in MSMoneySunset, and in Fund Manager, as well as in a 
GnuCash account.  GnuCash is outlier with respect to the fund basis 
data.  Thus the curiosity.
Another test made - If I change the value of the positive Jul earnings 
then the 31July2009 basis figure has still been reduced rather than 
increased.
