Can i just say Random Number Generator (R.N.G) cannot be fully Random in the sense of computer talk as computers cannot pick random number as they are programs(number algorithm). the number algorithm are normal linked to something like Date and time down to milliseconds to generate a number. so no mater when u click on the chest it will make no difference to what you get as in thinking 1st person opens it will get better stuff. the way i look at it. in say nightfall 3 team members in the game at the end there is a table E.G Table 1 1. weapon 2. Weapon 2 3. coins 4. armour 5. armour 2 Table 2 1 Weapons 2 3 Coins 4 armor 5 When you open a chest RNG spins and gives you a number (E.G you roll a 3 so you win Coins + Coins. as you see some table 2 does not have any wins) this is where i am not sure how they do it i think it is down to milliseconds of the time when you open it as it ranges from 0-9 doom nothing els need to be programmed as going to be impossible for a human to open a chest of the same millisecond every single time.

I fear Bungie will keep their loot table and "weighting algorithms" a secret. If we all knew the rules we could all do whatever might be necessary to bias the results. Some people here have started threads where they have done some sample analysis and, for example, decoded 1,000 blue engrams (or whatever) to find that there's something like a 1.2% chance of exotic (or whatever the real results were). If interested I'm sure Google might find some of those threads. But all that will tell you is what the chances are of X being pulled from Y. It won't help you to get X. Presumably this is all really about why you haven't got a Gjallarhorn and what you can do to influence the result? A bit like throwing dice or playing the lottery I think (assuming the Bungie mathematicians have done their work right) there is nothing you can do to force a particular result. A lot of people who have Gjallarhorn (or any exotic for that matter) have said that once you get an item once there seems to be more chance to get it again. That would suggest that Bungie are inspecting your inventory when weighting their loot table results. To be honest I haven't a clue why they'd do that but again this is based on sample analysis of a lot of people who have received a lot of exotics so if there is a trend it may be suggestive of the mechanism - again I don't see why unless it's to deliberately frustrate people? (or maybe they think that once you have got exotic Y for one character you should have more chance to get it again so you can also give copies to the other 2 characters?).

R.N.G Random. Number. Generator. Imagine a spinning slot machine with the numbers 0-9 on it, and five slots where these numbers come up. After a activity, opening a chest, or a drop during a raid, that slot machine spins and randomly selects five digits. You rolled 03617. Those numbers determine what loot you get. Those numbers are independently drawn and have no influence on the number after it. Granted this is not the system Bungie uses, but it gives you an idea of what happens. If your still in school, take a statistics class. Most usefull math I took during highschool.
