True, however in some cases you want to come close.  Take for
instance, really annoying threads that have gone on way too long you
actually want to make sure that it makes it below the 'mark' or
'expunge' values.  This will become increasingly hard to do if you
have a percentile based system.  The other problem is that it greatly
depends on the frequency with which you use gnus.  For instance, if
you read gnus 2-3 times a day, then every time you load the score file
your scores drop by a percentage.  Now, since very few articles will
get posted during that time, your scores will be aftected drasticlaly.
Then there is the guy that reads articles gnus once in a blue moon.
He'll barely decrease his scores upon load and then read, say, 100
articles with the same subject which will greatly increase the score
for that subject.  The guy that read the gnus 3 times a day probably
entered the group and had no articles with the subject in question,
and thereby only decreased his score.  I've certainly rambled about
this far long enough for even the most basic of infants could
understand my thoughts...  err, I could have written this so
incoherently that no-one will understand it either I suppose.  Wow.
Monday mornings.

Anyway, I like the suggestion at the end of the week about have a
variable that is a list contains the rules to use and when.  IE,

if abs(score) < 50 then decrease by 5 pts
if abs(score) >= 50 then decrease by 5%

or something of that nature.
