From there, you calculate the differences in surface angle alongside the distance. that tells you the rate of curve.
I've never actually heard that they calculated the rates and all of the angles for, say, an entire day at both sticks.
Long range gunnery tables
Ah, seems like theres an official military source in there, thanks.
The entirety of the GPS system relies on round earth.
I've heard that could just be high altitude balloons.
Maps and coordinate systems. Most maps and their respective coordinate systems are overlaid in such a way to account for the distortion from the creation of a two dimensional projection of a three-dimensional object. If these maps were inaccurate, ships, planes, trucks, and damn near anything else traveling significant distances would be unable to reach their destinations accurately. You can read more about the details of these projections here and here

The so-called ‘flat-Earth map’ is claimed to be distortion-free, and some flat-Earthers take that as proof of its correctness. In reality, a map can only be distortion-free if the actual shape it represents is also flat. But this is not the case as the Earth is a sphere.
lol, flat earth map is wrong because the earth is a sphere. I love that website sometimes.
Supposedly sailors used to crash and shit all the time because their maps were off and they couldn't understand why. I'd provide a link but It'd be to a like 6 hour Eric Dubay doc because I can't remember what part of it it was in.
Railways are made to minimize travel distance. Their routes would be different if the earth were flat. There are documents that can be found from early to present describing this. More info can again be found here:
Suspension bridges: The tops of the "towers" of some of the longest suspension bridges are a tiny bit farther apart (than the bottoms) to account for the difference. If the earth were flat or anything but round there, the difference would be a construction weakness and potentially ruin the bridge. Blueprints for these bridges will show this and likely show the reasoning behind it.
I love the one bridge that had 1 5/8 inches of compensation for earths curvature in it, as if a tolerance like that can be, or would even want to be held over such a long distance. Bridges like this are supposed to move a little like steel skyscrapers are made to sway.
So you're suggesting Q tells people what they want to hear rather than the truth? Do you understand what kind of implications that would have on everything said by Q?
Optics are important, yes.
Also I don't think you ever addressed the fact that I can clearly see, in it entirety and in a clear, non distorted image, something 25 miles away. I'm not really that hardcore of a flat earther even but I know the arguments on both sides.
Can do all sorts of experiments with the sticks. Hell, if you can't find someone else that's done it, it's not too hard of an experiment if you're careful. Maybe you could be the first!
GPS and other satellite systems are far too dynamic to be balloons. Signals drop in and out, some are stationary (geostationary orbit), some are high speed movement. Many of these systems rely on triangulation; that is to say measuring distances (likely often by measuring transmission delay) and using some fairly straightforward geometry to determine position on the ground. If you were to dig around enough and find the programs or some data from one of those calculations, you could see that the distances reported are properly aligned with round earth.
And that's without considering the satellites you can observe moving at high speeds in the night sky; too high of speeds for balloons.
That part of the map you've picked out is rightfully a pretty circular sentiment, but my original point of the differences in projections and so on stands regardless of that.
I'd need more context on the sailor thing. What time in history? Any time before satellite mapping will have some pretty big inaccuracies just because ground mapping is not easy and navigation wouldn't be as high accuracy or quality either [as in, getting "coordinate" positions or the likes].
The bridge compensation is still a pretty significant amount in engineering and construction. Just because it has the capacity to flex doesn't mean that the position when it comes to "true" isn't important. Hell, if that compensation weren't needed and the earth were flat, the natural resting position should be flexed towards equal distance at top and bottom, but it isn't.
For the final point, you'll need to provide more direct context. where can an image be seen, at what distance, of what. There are a lot of factors that come into play with stuff like that, just saying an ethereal "people can see an image 25 miles away without distortion and clear" isn't exactly a scientific argument. If it were, so would "Humans can see their toe when their foot is behind their head"; it's an unapproachable statement that can't be scientifically explained when left so detail-less and nebulous.

Source wise it traces back to this document: https://www.eugeneleeslover.com/USN-GUNS-AND-RANGE-TABLES/OP-770-1.html which admittedly could be faked, but I don't know if you could really get that much in a way of a direct military source for range tables for antique weapons systems.
