Trying to Understand the Math

I heard something about the budget cuts to the colleges being distributed by a 30%, 70% formula based on enrollment declines and credit hour generation to reach a goal of about $1.1 million in cuts -- with colleges with increasing enrollment getting budget increases. Unless the 2012 enrollment numbers I've seen are wildly wrong or other numbers listed in the last Fact book have changed drastically, I cannot figure out why there are enormous cuts planned for CASA and 5-digit increases planned for COB. If anyone has access to better data or formulas, please share. Sorry COEHS and COLA, but your cuts are explainable.

	2011 undergrad	2012 undergrad	change	% change	2010 credit hours generated	30/70 cut	70/30 cut

total without premajor	13518	13059	-459		225278
multiplier: 30% enrollment change, 70% credit hours			718.9542		-3.418
multiplier: 70% enrollment change, 30% credit hours			1677.56		-1.46486

Assumed formula:
Multiplier = (1100000 / total credit hours or change in number of students w/out premajors) * .3 or .7 as appropriate
Cut = (enrollment change * multiplier) + (credit hours generated * multiplier)
