That's not true. In this case it's pretty close to 0.5, but if you try to
change the threshold to 0.1 or 0.9 you'll see great differences. BTW, this
all assumes that the strength is 1; I'm sure that's what you meant too.

I can't remember the real formula right now, but it should be possible to
derive it from my easyblob macro, which you can find here:
