How is XP received calculated?

[ride the spiral]

Seem to run into this question a lot and everyone has a different take on it; seems like everyone is adamant they have the right answer. I'm curious how exactly group xp differs from solo xp. More specifically, how hybrids and pet classes effect group xp, and how pets effect solo xp. Here are some of the answers I have gotten or heard from others:

Examples of what I've heard:

SOLO

Non pet classes receive 100% of the xp from a given mob. (duh)

Pet Classes must do 1pt of dmg to gain 99% of the xp from the mob, and the pet will only take 1% of the xp. If said pet class fails to provide 1pt of dmg, pet eats entire xp, 99% of the xp, 75% of the xp, [insert figure with percentage here] xp, and pet class receives 1% of the xp, 25% of the xp, [insert figure with percentage here] xp, etc.

What does a pet class gain in terms of percentage of xp from the mob when it deals at least 1pt of dmg?

What does an enc/bard/charm class receive in terms of percentage of xp when a mob is actively charmed and has dealt dmg to the xp target of said class?

GROUP

When in a group with no hybrids each member of the group receives an exact portion of the xp (4 members in group, xp is divided by 1/4th and given to each of the players, etc).

When in a full group, members receive 1/6th of xp from mob and an additional amount of xp - thusly a "Full Group Bonus".

When hybrids or other class/race combos that have xp penalties are present in group, xp portion received by each member is less, or that hybrid/troll/what-have-you "soaks up" more of the xp, effectively denying others of said xp compared to if there wasn't any hybrids/trolls/what-have-yous.

When charming, charm mobs soak up 40% of xp from entire group. [You must be logged in to view images. Log in or Register.]

What is the formula for which to decipher how much xp each group member will receive in a given setup (clr, enc, war, rog, rog, rog vs. clr, brd, sk, rng, monk, wiz, etc.)? How do pets effect this formula? Furthermore, how do charmed mobs effect this formula?

Upon a lazy google search I came across the following:

Experience calculation

In order to calculate the experience gain a four step formula must be followed:

1. Calculate group bonus based on the number of PCs in your group

For N= 1 | 2 | 3 | 4 | 5 | 6
GB= 1.0 | 1.2 | 1.4 | 1.6 | 1.8 | 2.16

2. HCB = 1; if ML < 55 or PL < 50 or PL-ML > 5
HCB = 1.95 + ((ML - (PL-5)) × .13); otherwise.
3. B = ML × ML × ZEM × GB
4. XP = B × (PL + 5) / (S + (N × 5)) × HCB

Where:

ZEM = Zone Experience Modifier
ML = Mob Level
GB = Group Bonus (1)
HCB = High Con Bonus (2)
N = number of players in group
S = sum of levels in group
PL = player level
B = Base mob xp (3)
XP = EXP awarded to player (4)

If you look at the website that I quoted from you can see some of the information is incorrect according to classic, as it was updated to match the patching of atleast 2007 (I can't even think of what expansion this could be [You must be logged in to view images.

Literally every link I click on google search gives different results on how this works.

I apologize if this is posted somewhere apparent. I did a forum search, searched the library, and of course, resorted to google - admittedly half assed. [You must be logged in to view images. Log in or Register.]
