FYI @d-wasserman: Your original code for Create Percent Access Polygons checked whether a feature class was projected by looking at the SpatialReference.PCSCode property, and if it was 0, assuming it was not projected. I just discovered some state plane coordinate system that also had a PCSCode of 0. I have now switched the logic (which now lives in tool validation in the .tbx) to use SpatialReference.type != "Projected", which seems to work reliably.
