View analysis test

Hi ,
I am trying to test the View Analysis component on a simple test geometry of one single horizontal surface, without any context, and 0-Horizontal radial as viewType. My understanding is that this option will give me the percentage of a 360 band for each point that doesn’t meet any context. In that case, all the results should be 100% in my example, but the ones I get are all 20%. What am I missing?
Thanks

I think I solved this. I used 4 as an input to viewResolution and fixed it. If this was not coincidental, then it is solved. At first, this input seemed irrelevant since it says it is only used as a sky subdivision resolution parameter, but it worked.
