This is maxed Shadow Web?
32/1000 = 0.032
42/1430 = 0.029371 <-- anomaly
548/17000 = 0.032235
1306/40500 = 0.032247
1483/46000 = 0.032239
1580/49000 = 0.032245
1806/56000 = 0.03225
1887/58500 = 0.032256
I think we can say with confidence (except for that Scuba Pepe..) that it's a percentage of HP. Mathematica's "Rationalize" function returns the first accurate 'approximation' as 1/31.
1/31 = 0.032258
It seems like a strange number to use, but it's extremely accurate on your samples. And the next best rational number is 44/1365 = 0.032234, which is quite a bit more unwieldy.
(And of course, it has to be a rational number. Using an irrational would just be... irrational.)

A good sample, if it isn't too inconvenient for you, would be a Lucida or Dark Rash. They have 15500 HP, so Web should do exactly 500 damage to them if the damage is 1/31.

I've also come up with a theory for the other levels... maybe Web does 1/(51-skillLevel) of the monster's HP. Then it'd do 1/50, or 2% at level 1. That would account for the 2% figure from the other source.

It seems to make a lot of sense, but I think those Rash/Lucida samples should be gotten first.
