Hmm interesting theories no doubt. I have not allowed myself to read them all due to a lack of time which I seem to have and because of the hostility of several posts, which i find most disturbing.
Loot is random.
However, there are several constant-factors which we all have to accept about it. Without getting into detail, all those theories and most interesting methods about getting several or specific kinds of loot on specific locations are mostly true ( getting sudden ammo drops after using that ammo to defeat enemies among them ). There are of course certain situations in which there's no possible explanation save for randomness ( getting famed on pouchs, getting legendary weapons on considerably low levels ..... )- Still, through out my looting here at Potco, I've "tasted" each of this different methods, and I must say that they do have some use after all.
Some of these methods are based on mathematical reasoning taking into account chances and probability. All they do is establish protocols that can adapt one's looting behavior to these chances and percentages about the weapon-dropping-rate. I've found that some theories about several "looting servers" are correct up to a point. Sometimes a server has better loot than others, that IS a fact. A server that drops more skulls has more chances of dropping more famed and legendary weapons ( simple mathematical reasoning ). Think of it as if you were playing poker or BlackJack or any other card game. In Black Jack, there's more chances of getting black-jack if instead of having a card with a value of 10, you have an ace : if u have an ace, there are 16 other cards than can brighten your day; should you already have a card with the value of 10, there are now 4 other cards which can brighten your day, since there only 4 aces.... Of course, you'll tell me that that can be completely random depending on the way in which the croupier shuffles the cards, but it actually isn't, its just simple probability and maths.
There's the common mistake of misunderstanding a situation which handles low-probability-rates ( such as card games and looting ), with a situation in which things happen completely at random-----
One last comment : Disney says the "looting system" works at randomness. Now I wonder, taking into account the way Disney has abandoned Potco, is it really smart and wise to go for them when we want a good explanation about something game-related, when they cannot even protect a pirate-avatar from being disconnected by someone completely non-related to the account of that pirate-avatar or the computer which that player is using, managing to achieve this most coward goal with the simple use of some coding or third party program?
