Gestalt and Multiclassing Penalties?

[Luckanan]

I've read and re-read the Gestalt rules, and I can't find anything re. multiclassing and possible xp penalties...

When creating a Gestalt character, does each class have to be within 1 level of every other class, on BOTH sides?  (For the moment ignoring favored classes.)  Or do you look at each side of the Gestalt as a separate character progression and check for xp penalties one side at a time?

I think the latter makes since, but I'm looking for a RAW reference I can show my GM.

Thanks

I have a house ruling that permits my players to gestalt or not as they wish- but if they gestalt, they can't crossclass. Ever. No PrC's, no dips, nothing.
Makes em think long and hard about a character concept before they chose one way or another- and the powergamer of the group elected to single class

Most DMs hand wave it for sanity purposes.

The Gestalt game I'm playing in counts all classes at once.  If you're a Rogue3/Fighter4/Swashbuckler3/Wizard8 and you don't have Wizard as a favored class, you take the XP penalty.  That said, the DM also gives you one 'free' favored class over and above what's normal for your race.  So my half-elf effectively has TWO favored classes.  My build uses both, plus PrCs

Yeah, though most DMs I play with junk the multiclassing penalties anyway.

While having multiclass penalties in the first place is dumb, it's doable and understandable. But when you have something like an wildshape ranger 5/warshaper 4/master of many forms 10/fist of the forest 1\\rogue 16/scout 3/monk 1, my head begins to spin thinking about BAB and saves let alone multiclass penalties.
