How to judge?

At least once a week I receive email in similar wordings. That's of course
very nice stuff to read but what puzzles me is Rebel's progress through the
years in this respect.

I mean this: I am a 1800 player, very bad in tactics but with a positional
understanding of 2000, maybe a bit more. How to judge progress in Rebel's
positional understanding every time I add new chess knowledge?

Has Rebel improved in playing humans since version 8,9,10 and now Rebel
Century? To answer this question precise you have to realize that hardware
has improved too during the years and people tend not to play old versions
which makes it even more difficult to judge its progress.

Since times I use the following guide-line to decide which version is best:
- test sets (about 1000 positions) 30% as a first impression.
- auto232 results (30%)
- my personal impression based on my own style and feelings (40%) this
includes the GM challenge games as well.

How do other programmers decide which version is best? and maybe more
important which criteria is involved?

I also am curious on opinions if Rebel Century is clearly better than let's
say Rebel8 when the subject is playing style which is something different
than playing strength (my opinion and view).
