This is what I find so hard to understand in many cases. To have the
information "X is stronger than Y" is to me uninteresting unless
I know how much stronger it is, i.e. I want an estimate of the
average score. Some people seem to run matches and then declare
which program is strongest, but doesn't it really matter to them
if the average score is 50.000001% or 99.99999% ? And if you
want this number it has to be given with an estimate of the
uncertainty... Back to square one.

Contrary to what you are saying (which I snipped and now
am too lazy to restore) the information "X is stronger than Y"
only makes sense to me if e.g. you as a programmer were running
two close versions of your program against each other.
