Does the Bishop Experiment contradict that the Earth is a globe? [on hold]

According to the Flat Earth Society, the Bishop Experiment demonstrates it is possible to see Lighthouse Beach from Lovers Point and vice versa on a very clear and chilly day.
So:
IF the earth is a globe, and is 24,900 English statute miles in circumference, the surface of all standing water must have a certain degree of convexity--every part must be an arc of a circle. From the summit of any such arc there will exist a curvature or declination of 8 inches over the first statute mile. Over two miles the fall will be 32 inches; by the end of the third mile, 72 inches, or 6 feet, as shown in this chart.
Correcting for the height of the observer of about 20 inches, when looking at the opposite beach over 23 miles away there should be a bulge of water obscuring objects up to 300 feet above the far beach. There isn't. Even accounting for refraction, the amount hidden should be around 260 feet - seeing down to the shoreline should be impossible
Is above statement correct?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

"Does the above experiment proves the Earth is flat?" this seems to be too broad here (the answer is obviously "no" though). The other question seems on-topic, though I'm not sure how notable it really is. And even the users in the flat earth society forum don't believe it to be correct.

The page only describes what the person "Tom Bishop" says they did. No photographs, no names of witnesses, no external evidence. If I describe a trip in which I walked to the moon, that doesn't make it possible.

@kenorb -- The experiment says they take into account refraction, but according to my back-of-the-envelope calculations, in the brief description they've understated refraction by a factor of 10 or more.

I also note that Tom Bishop calculates the distance between his two points using Google Earth, a tool that assumes (and works only if) the Earth is round.
