Meta Pet Experience gain question

Upon studying the forums, I ran across a script of code that claimed to be the calculation for pet experience gain:

Mob hp=xp except when the mob's hp is less than:
Lvl 1: none
Lvl 2: 75
Lvl 3: 150
Lvl 4: 250
Lvl 5: 350
Lvl 6: 450
Lvl 7: ?? (Code did not include this)

Can anyone confirm this and/or reveal the threshold for level 7 experience?

Thanks
