glop_15 -- 39425s/4835h of 85945 corpus (70035s/15910h)
Some words matched by this rule:
# glop_15="recommendations"
# glop_15="disqualificatio" n
# glop_15="misunderstandin" g
# glop_15="extraordinarily"
# glop_15="interpretations"
# glop_15="Congratulations"
and a whole bunch of PGP signatures
Need I say more?
glop_20 -- 18578s/1376h of 85945 corpus (70035s/15910h)
glop_20="contractorswarehouse" .com (my domain)
glop_20="XXXXXOOOOOXOXOXOXOXO" (a boundary between sections of email)
glop_20="internationalization"
glop_20="NeuschwabenlandTimes"
glop_20="anthropomorphization"
glop_20="electrophysiological"
and a whole bunch of PGP signatures
glop_25 -- 5497s/205h of 85945 corpus (70035s/15910h)
glop_25="MMMMMMMMMMMMMMMMMMMMMMMMM"
glop_25="communityservicesincorpor"
glop_25="Bcccccccccccccccccccccccc"
glop_25="wwwwwwwwwwwwwwwwwwwwwwwww"
glop_25="XXXXXXXXXXXXXXXXXXXXXXXXX"
glop_25="futureofamericandemocracy"
glop_25="AlbertSherbertOrangehalfg"
glop_25="ZZZZZZZZZZZZZZZZZZZZZZZZZ"
glop_25="villagemarketHamBrownSuga"
glop_25="abcdefghijklmnopqrstuvwxy"
and a whole bunch of PGP signatures.
Most telling, I run with a 9.0 required hits threshold. Your three rules
resulted in 205 false positives (all ham that matched glop_25).
