Hey Randy,I don't know about your bug, but having sat through some of your TNGIC presentations, I can verify that you are, in fact, crazy... I've got a parcel base that's in EPSG:2274 and when I calc a comparable field (decimal; width:20; precision:5) using $area/43560, I get a value that is the same as in the calc_acre field for that same parcel (values inserted by the assessor), so it looks like it's working for me. I'm running v2.2 x64 installed with OSGeo4W on Windows 7 SP1. FYI, cats can be pretty sneaky...
