Help with what's missing from my XP formula
#1
My XP formula used to be correct for my  but I had not tested it since becoming 405+. I am now 411 and my understanding is it should be divided by 3 but it is a bit off. I also can test my alt who is 311 and the formula is perfect which makes me think maybe it is not just 1/3 xp as I was told.
Here is the formula I use for base XP and all of the multipliers with my current values for them.

BaseXP
    = EnemyLv * (1 + 0.003 * EnemyLv)
    = 21025 * (1 + 0.003 * 21025)
    = 1347176.875
Party Mod = 0.4
Party Boost = 1.5
XP Orb = 1.18
Total XP Boost
    = 1 + Ascension + Acct + Guild + Alter + Event + Support
    = 1 + 0.25      + 1.2  + 0.18  + 0.7   + 0.13  + 0.32
    = 3.15
Inferno Tier Bonus
    = 1 + 0.003 * Tier
    = 1 + 0.003 * 139
    = 1.417
Lv 410 Penalty = 1/3

This should calculate as...
1347176.875 * 0.4 * 1.5 * 1.18 * 3.15 * 1.417 / 3 = 1,419,113 but I'm getting 1,461K 

In trying to determine what is missing I need to determine if I'm missing a value added to a multiplier, or a new multiplier altogether. will assume 1,461K is rounded meaning between 1461000 & 1461499

If that missing variable added to current multipliers...
1461000 <= 1347176.875 * 0.4 * 1.5 * 1.18 * (3.15 + x) * 1.417 / 3 <= 1461499
...then 0.09298 <= x <= 0.09408
or between 9.3% and 9.4%

If it is an additional multiplier I am forgetting...
1461000 <= 1347176.875 * 0.4 * 1.5 * 1.18 * 3.15 * 1.417 * (1+x) / 3 <= 1461499
...then 0.02952 <= x <= 0.02987
or between 2.95% and 2.99%

After you reach level 200, each Inferno Tier will increase your gained experience by 0.3% and each 100 Inferno Tiers your experience will be boosted by 3%, as of Patch 0.60z.

So your formula is missing the 3% bonus from inferno tier 100+, which you don't have at your alt.

1,419,113 * 1.03 = 1,461,686 (looks like it rounds down, and you have your 1,461k)

Ah I remember that change but must have not remembered the 2nd part when I added it to my sheet and I wasn't far enough at the time to notice. Thanks a bunch.
