Order and Overall credit limit to match when setting up Recommendations

Trying to figure out how to make the Order and Overall credit limits match when configuring Recommendations. When changing just the overall limit by percentage, the change is made before the calculation for the order limit thereby making it different. Also, when limits are different to begin with, it changes the overall limit to the adjusted order limit after the adjustment and leaves the order limit the same as it was originally. I must be doing something wrong in the setup. Any help is appreciated. thanks
