Group EXP distribution online tool

This calculator assumes that all group members obtain the same percentage of exp per kill, regardless of total experience. It makes sense based on the way the wiki describes group experience distribution, but go group with a wide range of levels/classes and you'll see that that's not true.

Calculator is not broken, it is just displaying bad (well, misleading) information. The 'XP to Level' field is showing TOTAL experience needed to get to that level, as in, if you started from level 1 - not how much experience is needed, in this level, to level.

Let's take your example of a 40 and a 59. Let's choose something neutral - HUMAN WARRIOR.

First off, plug in the numbers:

40 HUMAN WARRIOR = 13.9% = EXP TO LEVEL = 74880000
59 HUMAN WARRIOR = 86.1% = EXP TO LEVEL = 462102750

Now, remember, that number is actually the TOTAL exp you'd have. To find out the actual number, tone the levels down on the tool to 39 and 58, to find the starting point:

39 HUMAN WARRIOR = EXP TO LEVEL = 64064520
58 HUMAN WARRIOR = EXP TO LEVEL = 403881840

So, Experience NEEDED to level:

40 WARRIOR = 74880000 - 62064520 = 10,815,480
59 WARRIOR = 462102750 - 403881840 = 58,220,920

So now let's make up an imaginary mob. Let's say the mob awards 1 million exp when it dies.

59 Warrior = 1,000,000*.861 = 861,000 exp
40 Warrior = 1,000,000*.139 = 139,000 exp

Mobs needed to level:

59 Warrior = 58,220,920 / 861,000 = 67.62 mobs to level
40 Warrior = 10,815,480 / 139,000 = 77.80 mobs to level

Clearly, each is not getting the same amount of experience. BTW, this was with two classes in a HELL level, which is why they're so close, actually. Change the 40 warrior to a 41 warrior and watch:

41 WARRIOR = 80637570 - 74880000 = 5,757,570 exp needed to level = 14.9% exp
59 WARRIOR = 462102750 - 403881840 = 58,220,920 exp needed = 85.1% exp

Mobs needed to level:

59 Warrior = 58,220,920 / 851,000 = 68.414 mobs needed to level
41 Warrior = 5,757,570 / 149,000 = 38.641 mobs to level

Now the tables have turned, and the 41 warrior is leveling almost TWICE as fast as the 59!

This is due to what's known as the "HELL MOD". Hell Mod is used in calcuation of total exp needed to level = level^3 * class_penalty * race_penalty * HELL_MOD.

Whenever your hell mod increments, 'total exp needed' takes a shift upwards as it compounds into the equation. While you're in the same hell mod, your only change is in your Level^3.

This is why you see the differences - especially in the 50s. Almost every level has a new hell mod (and they jump twice in 'super hell' - 54 and 59). The idea of 'leveling at the same time' only applies when all the entities are within the same hell subgroup.
