I'm trying to figure out how to code a scoring recipe of "each match
adds $weight, the score will not exceed $max". If I understand the
procmailsc man page correctly, I have to compute x each time from $max
and $weight (x = 1 - (w/m)). Is there an easier/better way?
Sorry for following up to my own message...I solved this by
pre-computing w for a handful of m and x values. If there's a better
way, I'm still interested.

# These macros are used with procmail's scoring; here's how: The
# first number in the macro is the desired maxiumum score (from the list
# above), the second value is the exponet (*100) which should be used to
# obtain that score with the macro.
#
# For example, if you wanted a maximum of $SPAMCHECK_50 with a growth
# of 0.33, you'd use
# :0
# * $${SPAMCHECK_50_33}^0.33 <regexp>
# With this, the score will never grow larger than $SPAMCHECK_50
# Values computed by w = m * (1 - x), see procmailsc for details.
# with exponents of x = {0.01, 0.1, 0.25, 0.33, 0.5, 0.67, 0.75, 0.9, 0.99}
