I read your first reply above a while ago and have/had been trying to think of a 'tactful' way of telling you that you were wrong :) (..and most likely fixating on some bad test-cases). ... So I'm pleased (and relieved) to hear that you went back and looked again and discovered the problem!

Anyway, don't focus too much on finding the trouble with the .pyd version of the script... when I was reviewin the previous thread earlier, right near the end you reported a problem where apparently the weighting is messed up in the .pyd.  It also looks like I never got around to looking into that, so I suspect that's where the problem is (you could take a look at your .vwt files - you might see all 0/1/0, 1/0/0, 0/0/1 weights, for example).
