the angles you've labeled 50% dark and 25% dark do not have the relationship to luminosity you think they do. luminosity is the word for what percentage of the moon's area is seen as lit, so in math terms, 'dark' is the Y coordinate of the end of the line between light and dark expressed as a percentage. i.e. 100 * (y + 1)/2, or (y+1) * 50
A 45 degree angle from the center of the moon, aka your claim of 25% dark, would actually appear to be 15% dark. (-rt2/2 + 1) * 50 = 14.6447%
The angle required for 5% dark / 95% luminous is 64 degrees down from the center of the moon.
(after double checking my drawing, this angle is more like 64 degrees than 60.
the 6.7% for 60° numbers are correct, but what's actually seen is closer to 5% and 64° instead)

saying 'I win' isn't the same as winning, right? so when I write, 'his argument was pretty finely ground up,' I know that doesn't prove he lost. but I find it worth pointing out that Tom felt the need to respond in kind but with STRONGER LANGUAGE
DEMOLISHEDgo ahead, look at the numbers in that thread. tom doesn't know what he's talking about
one hopes some of the smarter flat Earth believers here can do trig. CS PhD Dr. Pseudonym can barely help himself from jumping to nitpick and correct people - pete where you at with helping Tommy B do math
