When I'm not a work I'll get more details, but regards tables in Pathfinder that converts CL to XP, and through a simple add up the levels of each player allows for a budget of XP values x level of difficulty to "purchase" opposing monsters based on that budget.

It really works well with varying levels of PCs in a party vs. varying levels of opponents like 1 BBEG and 2 to 10 lesser minions. Much faster to create encounters.

There is a third party "Pathfinder compatible" product coming out called Trailblazer that further develops this idea into a quick math exercise making it even easier.

I'll post more details tonight.
