I'm working on a bunch of graphs of accuracy over different types of
training.  It's just taking me a bit longer than expected (I'm having to
deal with cracked machines at the moment).

For building the graphs, I already have a testing harness which sorts
and processes the messages in a linear fashion, with various rules for
whether to train on a message or not.  This sounds like just another
rule for it.

Yes.  It'd also be a great source for rules for my testing harness.
If you make the doc, I may be able to provide graphs of accuracy to
go with it...
