That’s not a constant on the ground because you have different elevation levels that can cause the line of sight to be farther or closer depending on the terrain. There are several variables that will affect line of sight on land. A slight hill in between the two locations can cause a shorter line of sight whereas a slight dip between the two locations can cause a longer line of sight. The elevation that your viewing from isn’t the only elevation factor that must be considered, the elevation your looking at also plays a significant role. You can see mountains much farther than you can see valleys.
When people who are doing flat earth measurements they usually do this over water.
There is a large lake near me (30 miles away) if i was to go and take a photo of the bridge going across the lake. Which is 9 miles from the spillway.
And i take my photo from 3 feet off of the water then according to this calculation of this earth curve calculator the bridge should be hidden 31 ft because of the earths curve
