Certain Modifiers - Explanation? E.g. Fine Motor Skill, Pain Shock Time, Heart Rate

[quick mango]

Any explaination what exactly "fine motor skill", "heart rate", "pain shock time" do?

Like i found out some things by playing but am not sure at all

Like fine motor seems to reduce time of item interaction (loading mags, healing)?

Got no clue what Pain Shock really does.
Is it the aim punch? The blurry vision? What exactly would reduce with the pain shock time

And how does heart rate affect me? Is it aiming / how much sway one has?

Would love a compendium of some sorts, either player made or as in a wiki / ingame codex

If you open you character windows with all modificators and hover mouse cursor over skills - you get more detailed info about

Thats good to know

Does it also explain Pain Shock effect and such? Or only active modifiers?

Not sure about whole list.

Pain shock - you can get knocked sometimes if get a lot of damage, or may be when few of your bodyparts destroyed at one moment. And you can only crawl about 15 secods if you don't have pain killer to use. This time can be decreased by modificator.

Heart rate modifies your running and aiming (your hands stamina depleted faster with high heart rate). May be something else too
