Many people use lootshare, but do we really know what its all about? Hopefully i can explain to you the lootshare system and show how it really works. All observations are by me and are my own opinoin.
The Truth
'LootShare is an entirely optional way for you and your clan to share monster drops in multiway combat areas. The sharing of items is fair, and is designed to ensure that everyone receives an equivalent value of rewards over a period of time. Alternatively, your clan can activate CoinShare to receive high-value drops as cash, which is automatically split equally between all LootSharers.
If you are unlucky enough to receive a small, or less valuable, share of the monster's drops this time round, then you will be much more likely to receive a better share in the future. This way, everyone sharing loot should receive an equal share, given enough time! Note that the distribution of drops is based on the market value of items (as determined by players trading on the Grand Exchange) rather than the shop price."
"When an item is dropped, its value is calculated using the Grand Exchange. Each player is given a 'virtual' share of that value in LootShare points. The system then chooses a player to receive the drop. The system looks at the points for all players in the group and whoever has the most LootShare points stands the greatest chance of getting the drop."
"The person who gets the drop then 'pays' for the drop in those same points, thus reducing the chance that player will get the next drop. So, if someone else in your group gets a valuable drop, your LootShare points and chances for the next drop increase a lot. If they get a less valuable drop, your points increase by less. "
"These points are stored from game session to session, but they will tend towards zero by a percentage every day. ""

Facts:
- Lootshare points are based on the grand exchange price of the item Dropped
You "pay" for your drop in lootshare points
Your points dimish each day
Some examples:
Ok, so we want to know how lootshare points work. Firstly lets assume three players, Bill, Todd and Fred are budding young monster hunters, about to start their monster hunting career. They decide to go to bandos godwars, on this particular day a Bandos Hilt is worth 30m coins on the g.e, and a Bandos Chest is worth 10m coins on the g.e. They decide to use lootshare as their means of splitting drops. All players have a 0 lootshare score, as they have never used it before.
They enter bandos godwars and the First Drop is a R2H, worth 40,000 Coins. All player recieve 13,333 lsp, As all three players have 0 lsp to begin, they all have a 33% chance of getting the drop each. It just so happens that Bill Gets the Drop. This means he is now at a 0 lootshare points position once again, Todd and Fred now have 13k lsp.
On the second kill they get lucky and recieve a bandos hilt drop! Bill has 0 Lootshare points at this stage, Todd and Fred both have 13k lootshare points. The bandos hilt is worth 30,000,000 coins. Therefore, as the hilt is dropped, each player is dealt 10,000,000 lootshare points for the drop. Now Bill has 10,013,000 lootshare points, and Todd and Fred Both have 10,000,000. This means that Bill has a 33.30% chance of getting the hilt, whilst Todd and Fred have a 33.35% chance of recieving a hilt. It's Freds Lucky day and the hilt so happens to go to him. He loses his 10,000,000 lsp as payment for the hilt.
The third kill and these boys are on a serious lucky streak, as they recieve a bandos chestplate! This is worth a total of 10,000,000gp, therefore Todd, Fred and Bill all recieve 3,333,333 lootshare points. At this stage, Fred who hasnt recieved anything, has 10,013,000 lootshare points, Bill who recieved the R2H has 10,000,000 Lootshare points, and Fred who recieved the bandos hilt has 13,000 points. This means that Fred has a 44.45% chance of recieving the chest, Bill has a 44.41% chance of recieving the chest, whilst Fred only has an 11.14% Chance of recieving the chest.
As you can see, lootshare points move around quite fast, and can drastically affect the chance of recieving a drop. Though that is the case, the larger the drop is, the less affect lootshare points has, as the points are awarded for the drop before the drop is decided on who it goes to, therefore points already in existance are diluted alot. You can see this when looking at Bill who recieved the R2H, even though he has less lootshare points, the bandos hilt is worth so much that it dilutes the fact of Bill missing drops earlier by a great deal, and in the end he only has 0.05% chance LESS of recieving the hilt than anyone else, which is a very small amount.
Real Applications
In a situation like at the corporeal beast, when people yell "GF LSP" when someone used to recieve a regen brace, they were obviously ill informed and pretty stupid. Because the G.E Price of a sigil is so high compared to the 1mil of a brace, it hardly makes a difference to the chance of recieving a good drop when the beast dies, as the 1mil is diluted among the high value of the sigil. On an even playing field if 3 people go that have never used LSP, and someone recieved a Regen Brace, then the Next drop an Elysian Sigil is dropped, the person who recieved the regen brace only has a 0.33% chance LESS than the other two of recieving a drop (33.44% chance of the people getting the drop who didnt get the brace compared to a 33.11% chance for getting the drop from the person who did recieve the brace)
Concluding
So what does this mean for you? Well, no one can actually know their lootshare points, unless they leave them long enough until they are at 0, then record their points as they get them. But really, that is very time consuming and gives no benifit to you actually recieving a drop. The chance of getting a very valuable drop from having more lootshare points is actually very low, therefore lootshare points serve no real purpose before actually recieving a large drop. The only time lootshare points really have any affect is after someone recieves a large drop, as you can see when Fred is there for the bandos chest drop, his chance of receiving the drop is very low, not that he cares because he just recieved a bandos hilt
I hope this helps to clear out a few of the lootshare points myths going around.
