My bad, I meant A1401, not D1401. A1401 has a value of 45, but it's
all the same, since 29 other patterns in the owl_attackpats database
have the same value.

Well then, I'll include it in an upcoming misc owl tuning patch.

The issue here is CPU power I guess. I started trying to use some
distributed computing here at my office, but our few poor old boxes
won't allow me to do an extensive job like this one I think. Sigh...
