For angrr:
First of all, if you want an in-depth explenation how this system works, I am going to refer you to http://code.google.com/p/epgp/.
I am going to explain you in dumbed down english how this system works in this post.
What does EPGP stands for?
It stands for Earned Points Gear Points
What are EP's
EP = Earned Points
EP's are points which you get while raiding or while being reserve during a raid.
Currently, 5 points are awarded every 10 minutes to everyone in the raid.
EP's are used to calculate the formula which determines your PR (Priority) which determines who should get the loot.
The higher your EP's, the better it is.
What are GP's
GP=Gear Points
GP's are points which you get after receiving loot.
Each item in the game has got a value based on several factors as set by blizzard.
GP's slow down the rate at which you gather PR (Priority).
As an example, if you got GP's, you might receive only 0.5 points every 10 minutes instead of the 5 points that are being given to people with 0 GP's.
What is PR
PR=Priority
PR is the actual DKP, PR determines who gets loot.
The higher your PR the higher the chance is you get loot.
PR is calculated as follows : Take the EP devide them by GP, and the result of that is PR.
What is the 10% Decay about
After each raid we decay (remove) 10% of all EP's and GP's.
What this does is if you received an item, it will lower your GP which will increase the speed at which you gain points the next raid.
It will also decrease your EP's to slow down the speed at which the guys with highest EP and PR gain points.
Why is there a 10% Decay
It is there to stop people from hoarding points, saving up for items that drop in black temple.
It is not possible to hoard points since people that do spend points to get gear are able to catch up with people who do not spend their points.
It will also help new recruits to catch up with the 'veterans' in the guild after a certain amount of time.
Example
Right so let's try this in practise with fictional numbers.
Monday's Raid
On monday Rowlow ended up with the following fictional points :
5 EP per 10 minutes, however he only gets 0.5 points due to GP's.
465 EP
333 GP
1.3963 PR
After the raid a 10% decay was applied, so Rowlow ended up with :
418.5 EP
299.7 GP
1.3963 PR
Tuesday's Raid
On tuesday's raid people still get 5 EP per 10 minutes, however because of the 10% decay from last raid Rowlow gets more points per 10 minutes then last raid, he might get 0.8 EP per 10 minutes.
