Subject: Value of playing different versions of a program against each other

Hi all,

What do people think about playing different versions of your program against
each other as a way of testing?

I'm playing around with it right now, between v0.07 and a newer version of my
program. The newer version is winning handsomely: +24,=18,-10.

This implies a reasonably impressive increase in strength, almost 100 ELO. Ok,
ok, it's a small sample, so the margin of error could be big.

However, my gut feel is that playing different versions of your programs tends
to overstate the strength differences. What do people think?
