No. I mean that a similar spam from the same spammer that's not been
learned will hit 50.

The way that bayes performs on retest isn't a reliable predictor of how
it will perform on subsequent new spams. The fact that a single spam
went to from 50 to 99 doesn't imply that the rest of the that type of
spam is easy to learn.
