If you take 2 weeks off and draw the MediCal short straw more than average, and don't get any lucrative ENT ASC assignments, you're not making your house payment. Of course, you make it up the next month when you are working 20 days straight. Over the year it should all work itself out. There are ways to work any system. Collusion will get you fired though. One job I considered in CA was hiring because of this very problem. They had recently fired 2 partners for unethically manipulating the schedule to their advantage. It was not a well thought out plan as the books are not secret and there were only 10 of them. It didn't take long for the managing partner, the one that signs all the checks, to notice that 2 of the guys were consistently getting a higher check than everyone else in the group. They all took turns assigning the cases and those two were using insurance information from the hospital database to set the assignments for the day. They were actually so desperate to get another body there ASAP that they dropped the partnership track down from 2 to 1 year. Losing 20% of the workforce for several months has a way of decreasing morale.

The location was OK, but not any great draw and you needed a Peds fellowship, so there's a limited pool of applicants.
Pooled units is great if you can get it. It makes things very fair. Especially in places like CA where the difference between MCal and insurance is often >3 times.
