How about this: maybe we should stop capping the per-word spamicity at
0.01 and 0.99. Let the uncapped values determine what words make it into
the extrema array. Then, before running the Bayes-like combination on the
extrema, cap the values as before, or apply a curve to the values to get
them to fit.
The capping is needed because unless you change the Bayes-like
calculation, any values very near 0 very near or greater than 1 will
override all the other values.
