I didn't give you a downvote.

Reading the above, I realized it could be misunderstood.
Thank-you, that's very kind. But to be honest, I take voting with a grain of salt. It's a type of social credit score. Not interested. I might give an upvote to a great post, and some jerk with an axe to grind comes along and adds a downvote. So the votes here may or may not be accurate. Some people will down vote just because they can, or because they have a bee in their bonnet.

Years ago in forum settings there was no such thing as voting or scores. People figured out for themselves what a worthy post was or not, and that was that. After awhile you can see who is worth paying attention to, or not. 

It's the younger generations brought up on FB and Instagram, etc., that rely on their "likes," to feed their fragile ego. ;)

You can test GE vs FE easily if you climb a small hill or mountain.

On FE, the horizon should be at the same level as your eye level. It should lay in the same vertical plane than the vanishing point.

On GE, the horizon should dip below your eye level. It shoud lay below the vertical plane of your vanishing point.

So we use the water level:


Wasn't that easy? On FE, the horizon should converge with the water level.

@ 42oN, at solar noon, the angle of inclination to the sun was 26o using a theodolite app.

The sky is overcast where I live, unfortunately.
