Power Leveling Battle Pets

As mentioned before, I was a bit lazy with respect to pet battles. I pretty much relied on Beast types -- the combination of the DPS and the bonus against Critters (which I've found to be predominant among wild pets) meant that leveling up beasts was pretty simple.  My Ravager Hatchling used Devour to heal itself and minimize trips to the stable master.  My spiders would web and suck life.  Life was easy.

And then I hit the master tamers. Or rather, then I met the master tamers and they hit back. Hard. Yeah, this team of beasts ain't gonna cut the mustard anymore.

So, now I have to actually use the mechanics of pet battles and have an honest to goodness team of multiple pet families with varying abilities (i.e. my Fledgling Nether Ray which is a Flying pet that has Magic, Beast, Elemental, Flying, Undead and Dragonkin abilities).

Enter attempts to Power Level.

I've tried a few methods flopping about in comments on the web.

1. Use two level 25 pets in Pandaria against level 25 opponents and just ensure the low pet (the power-levelee) does a single attack / buff.
2. Use two level 25 pets and ensure the low pet makes the killing blow (dots are excellent for this).
3. Use one level 25 pet and two low pets.

What I just read (check out the Experience Table on WoWWikki) makes me question this.  Unless I'm not getting something, it will probably be faster to simply level up a team of similar pets.   Essentially, you get bonus experience for leveling (i.e. the Difficulty bonus) if the pet(s) you're battling are two or more levels higher. In other words, if you are battling level 21s with a level 15, you would get the exact same bonus for the low pet if you were fighting against a level 17.

Plus, the experience earned in the fight is shared across each pet that participates. So, if all three of my pets participate, and two of them are level 25, there is absolutely no reason to use the max level because all they are doing is sucking up 2/3 of the available experience.

Hmm.

I think I'm gonna just pack a bunch of same or similar level pets and grind out battles near a stable master.  

I'll post back on how it goes.  Who knows?  I may even finally catch the damn Scourged Whelpling  that has eluded me to date!
