bogotune and "exhaustion"

[Tom Allison]

Ran into a cute catch-22.

bogotune wants a sample size that includes some high scoring ham and low 
scoring spam (maybe) to get a good calculation of what to set the 
parameters at.

run corrections to exhaustion tends to remove that high scoring ham, 
giving you a big fat remark and a shortened bogotune output.

So, it seems that I can do one or the other but not both on my archives.
Or I'm doing something wrong.
