Epic Challenge Rating and Rewards

[Feralventas]

Hey there Playgrounders,

I've got a party that's nearing epic levels, and I've started pulling from the Epic Level Handbook for some of the more challenging/dangerous/dramatic scenes here and there, but I'm having a difficult time locating an xp value chart beyond the 20th level cap in the DMG. Is there another book I should be looking into, or perhaps or should I simply run the numbers on the DMG chart and do my best to find a pattern and apply it up past CR21?

I think the small print under the XP by CR chart in the DMG talks about how to increase the experience amount for creatures over CR20 or w/e. I can post it for you if you are having trouble finding it, but it's pretty straightforward.
