Your Wiki says 3,000 miles:
"Modern Mechanics describes how on a Flat Earth the sun can be computed to 3,000 miles via triangulation
whereas on a globe earth those same angles can calculate the sun to nearly 93 million miles away"
https://wiki.tfes.org/Distance_to_the_SunBut Rowbowtham says it is "considerably less than 700 miles...
Hence it is demonstrable that the distance of the sun over that part of the earth to which it is vertical is only 700 statute miles. By the same mode it may be ascertained that the distance from London of that part of the earth where the sun was vertical at the time (July 13th, 1870) the above observations were taken, was only 400 statute miles, as shown by dividing the base-line L, D, by the distance B, L. If any allowance is to be made for refraction--which, no doubt, exists where the sun's rays have to pass through a medium, the atmosphere, which gradually increases in density as it approaches the earth's surface--it will considerably diminish the above-named distance of the sun; so that it is perfectly safe to affirm that the under edge of the sun is considerably less than 700 statute miles above the earth.

And what are you doing to determine the true distance?
I have suggested you guys experiment on this, taking observations from a few points and triangulating but haven't had much response.
