You've just made me think about another point where the sun we observe does not behave like an FE sun should: change of angular position during the day.
Okay, to keep it simple, we'll take a 12 hour day (an equinox) at the equator, where the sun does near enough to a 180° arc overhead. That's 15° per hour which, if you go out and observe the sun for one day, you can easily confirm. (This can easily be confirmed away from the equator too, just incline your angle measuring device to suit your latitude)
The problem with the FE sun model is that, if the sun moves the way they say it does, it would appear to move far more slowly in the morning and afternoon, and very quickly around midday. Similar to the effect you get when a plane flies overhead.
