Question about damage calculations (any dev?)

I'll just start saying that I think the valheim fandom wiki is completely wrong in every way and the formulas used there are outdated from vanilla before the combat rework.

I would like to know exactly what's the formula for combat in valheim because I just can't understand it. Block armor and block force, parry and failure to parry, how max health affect block and stamina usage. (and difficulty multipliers, like in a group or hard/hardest mode)

Some example is appretiated, for example

"A regular troll will deal 60 damage with normal attack, if you have 30 armor, you'll take 30 damage. If you're using a one handed with 20 parry and 1.5 parry bonus you'll parry for 30 and stagger the troll, but if you're in a party, the troll will deal 62.4 damage and you'll fail the parry"

I've tried to parry some mobs and looks like it depends on my max health. I can fully parry a lox on hard with 90 armor and 150 health, but if I try the same with 110 health I fail to parry and take almost 100 damage… Something feels off. Having a really difficult time on hard mode
