Dragon Level Up information

[dashcunning]

Where did the experience numbers come from? The reason I ask is because they aren't entirely accurate as far as I can tell. Or is there some modifier I am unaware of?

Crushing Blow: gives 34 xp, listed as 34 xp
Hunt: gives 9, listed as 17
Lightning (not fully upgraded): gives 17, listed as 30
Mana (not fully upgraded): gives 13, listed as 24
Egg (not fully upgraded): gives 9, listed as 17
Dive (not fully upgraded): gives 28, listed as 17
Wall, Phantoms, and Lava: untested

Results are from an impossible game (70% dragon xp) with 1 level in Dragonslayer (+10% dragon xp) and Training (+20% dragon xp). Assuming the Crushing Blow numbers are accurate, this implies the dragon xp bonuses are additive (70+10+20=100). For all the results, leadership of army was well below that of the enemy which, again assuming the Crushing Blow numbers are correct, implies the (enemy Leadership)/(your leadership) modifier maxes at 1, which seems sensible.

Are the OP's numbers incorrect or am I missing something?

Edit:
Interestingly, everything is off by about the same percentage amount
Hunt:53%
Lightning:57%
Mana:54%
Egg:53%
Dive:164%, which is 60% the other way.
