Hi KLCarch:

___Nice post with excellent detail. Now I know why you are a hypermiler

___The larger the ICE, the less parasitic losses an A/C unit will have on it. The HCH’s smallish ICE takes a pretty big hit with A/C. As long as you know the actual hit, you can decide when A/C is mandatory and or when it is optional. I bet you will be using it more as an option from now on

___Good Luck
