There's no reason they'd ever not rotate, correct? The Earth's rotation is constant; and we're talking about the same physical device, after all.
There's no reason that they'd 'rotate' in the wrong direction, as the supposition is that their rotation is induced by the Earth. At the very least, the device would correct itself over time in both of these examples.
They don't. Anyway, the pendulum is silly.
Let's discuss the curvature measurement. The Earth's curve is a constant. You got very excited at your redundancy, changing the angle of observation changes the angle of observation. Well done. At least I know that you're aware of this.
I'm on the shoreline. This means I am at sea-level. I'm 6 feet tall. I can sit in a chair and witness this. We'll say in the chair that I'm 4 feet tall, when it's probably more like 3 feet tall in a beach chair. There should be a 9 foot wall of water in front of the boat. And yet... I can see the ocean behind the boat. The ocean should be 9 feet out-of-sight. Quite a lot of missing curvature. That's not possible on a ball.
You'll say refraction, I'll say to myself 'why does literally everyone think that refraction could ever possibly do this', and that'll probably be the end of this.
You should try this yourself since it's easy to do. See what you find.
These devices have failed. Often.
