What's contradictory? The sun remained the same size, as predicted.
The filter had no effect, as predicted:
You don't have any model which predicts anything, you're giving yourself way too much credit.
All your model says is that the earth is flat, everything else is rationalisation to try and explain away the problems that causes.
If the sun revolves around a flat earth then clearly it will keep getting bigger and smaller.
So you rationalise and claim there is some effect which by amazing co-incidence exactly counteracts that.
I'm not a huge fan of Occam's Razor but as you invoke it, what is the simplest explanation for the sun remaining a constant size?
1) That the sun is getting closer and further away but there is an effect which only works on the sun and exactly counteracts the effect of the distance variation
2) The sun is indeed a constant distance.
You cherry pick pictures which show lights with extreme glare where you really can't see the size of the actual light source. In most photos of a row of lights going into the distance it's clear the further away ones are smaller.
Sunset cannot work by perspective, EA is a better theory which would explain sunset. Probably has other problems but it fixes this.
