Unarmed or Melee? (and other combat questions)

Also from my experience weight in Opportunity Knock seems to have no effect on the skill itself. It increases opening by the fraction of already existing opening (40% at 1 card).

So if opening is 40% Knock will boost it by 16% and result in 56% opening.

What do you mean? At equal weight, if the target is at 40% opening, a 40% reduction should put it at a 64% opening if I'm doing the math right. To clarify it further, Chop creates a 15% opening, and at equal weight, would take that 40% to 49%.

the amount of UA doesnt change the weight of the opp knock however the amount of stacks in it does change it, up to a maximum of 0.4*1.5. And your calculations are wrong you count openings like this (0.16*0.40=0.064) + 0.16 = 0.224 opening.

edit: nvm that last part i read your message wrong xd

From what i see OP-Knock does not create opening like other combat moves, in increases EXISTING part of the opening by 40%. It is really effective at pushing animals to near-100% opening. You punch few times, then 2-3 OP-knock and each of them is stronger than previous one (unlike regular attacks, which become weaker and weaker in terms of opening).

I was able to get 98% green on boar in just few punches + 3 OP-knocks.

TLDR:
OP-Knock does increase existing opening by 40%, NOT reduce protection (block) by 40% (like regular attacks).
And thus is not affected by UA, only by card count.
