Since there was a patch, and experience gains got changed, I decided to do another round of tests and see if there had been any changes.
The answer to that is yes.
Experience tank in the ability tree now works as intended. There was a considerable difference between having it and not having it.
I did a round of tests and logged the results, then reset my abilities and put them into experience tanks. Then waited an hour or so, and did another round of tests.
For me, with 100% posting bonus, 30 points into tanks (90%), 66% from adept learner and 5 normal auras (25%), the total increase was roughly 33%.
And with the formula that auras are multiplicative, and the other additive. that measures up to a a pretty decent result.

CODE
$get_exp = ceil( $get_exp * $aurabonus * (1 + $hathperkbonus / 100) * (1 + ($skillbonus + $trainbonus + $toplistbonus + $postbonus) / 100) );
Since auras are added separately, they can be removed from the equation, so what we got is
(base100+postbonus+adeptlearner+exptanks)
For me that would mean a total of 266 without exp tanks and 356 with.
And 266*1.338 is 356.
Or if you will, the expected increase from experience tanks matches up very closely to the achieved results.
So the question is, what was wrong before?
What did patch change?
It seems that experience gained per fight took a dive after the patch, is it possible that the code was messed up so everyone had full exp tank bonus all the time, even without having put any points into it?
Unfortunately, I don't have any logs from before the patch that are usable for a comparison, so I can't answer that.
But anyways, with the new patch, experience tanks works.
Just keep in mind that 33 points into them (almost 100% increase) will not double your experience.
But you will see a difference.
