This controller already goes WAY beyond what your average installer knows. Why not add a few more options to make it a little more efficient? I do agree with keeping it affordable, so the anemometer should be optional add-on to the weather station. Lets take for example the central valley. Wind is a BIG issue here, is pretty much a daily occurrence, has a HUGE effect on AE, and no monthly ave will ever cut it. Another thing I didn't note before, I saw no option for meeting leaching requirements. Unfortunately not all of us have high quality water to work with.
