Setting some guideline to assigning encumbrance to wearable storage items

[Salty-Panda]

Is your feature request related to a problem? Please describe.

Currently, the values are imbalanced and all over the place.
Using holsters, sheaths and tactical equipment is just inefficient. It's better to stack armor and cargo clothes in a single slot instead of storing bandages in your armor item

SWAT armor after filling up its 5L of storage increases in encumbrance by a total of 39 points

Describe the solution you'd like

Calculating an item's to-hit-chance has a clear guideline in docs. A uniform ruleset could be created and applied to storage items so there would be less unrealistic min-maxing with weird combinations of clothes and balancing commits based on a single person's opinion.

Describe alternatives you've considered

Additional context

Realistically, we are interested in two values: encumbrance/volume and encumbrance/weight.
Example criteria could be:

• lever rule/distance from the center of mass:
  some multiplier based on a body part, growing in the order torso < head < legs < arms < feet and hands
• bulkiness/rigidity:
  a few semi-rigid pockets (e.g. magazine holders) account for less encumbrance than a single loose sack/backpack. Applies for most armor with small pockets vs various bags and sacks.
• interfering with moves:
  is content lose or strapped tightly, can it bump into a body part? Applies for most belts, holsters, back scabbards, harness that can store gun
• coverage to weight/volume ratio:
  the better spread of cargo over body the better. MOLLE pack or runner pack is better than a shoulder bag
• clothing layer:
  not sure about this one. On the one hand pocket "close to skin" should be less encumbering since it's nearer the body so there is less inertia. On the other hand, if there are clothes in the further layer then there should be some penalty for bulkiness underneath them

Adding a definition for what quality a pocket uses would be good. A kevlar reinforce duster or cargo pants are going to have some pretty tough pockets, so volume is the only real limit to the pocket. Vs an LBE hook or extra-dimensional pocket, where volume is essentially meaningless.

Closing as stale, since stalebot can't do this by itself.
