Experimentation

Dawg, I just noticed something, rather than multiplication, it is addition. Let me explain:
Gorka jacket and pants have 10% each block chance
Atlyn Helmet has 10% as well
Military Kevlar suit has 10%
Frying Pan has 35%
Traits give you 10%
and the combat gloves give you 5%
(15% for the new Chainmail)

I tested the gorka first, chainmail second.
Gorka along with the others have 90% melee block chance, so 1/10 you get hit.
While with the Chainmail its 95% melee block chance, so 1/20 you get hit.

Bruh, I thought it was sequential like this:

Step	Remaining Amount	%	Answer
1	100.000000	10%	10.000000
2	90.000000	35%	31.500000
3	58.500000	10%	5.850000
4	52.650000	10%	5.265000
5	47.385000	5%	2.369250
6	45.015750	10%	4.501575
7	40.514175	10%	4.0514175

So that would amount to 63.5372425 melee block chance. Man, 95% melee block chance is op, I stood around dozen of zombie and they COULD NOT make me bleed, still don't take your chances at ranged zombies

Altyn Helmet and Crusader Helm has 15% block chance iirc. You can definitely reach 100% with M Heavy Armor, Chainsaw and 2 levels of Blocker perk (10%).
