I dare to say that despite pretending to know so much about the moon and the hoaxes surrounding it, flat Earthers cannot make a single prediction about the moon. Am I wrong?
You think a group of people could keep track of the behavior of the moon over a period of months or years and not be able to make a single prediction about its behavior? I dare to say I don't think you are actually using your head at all if you'd suggest such a thing. Anyone can take notes on the cycles of waxing and waning and look for patterns that repeat.
Yet, they don't. Isn't it strange? Everything is there. Whole tables of the positions of the stars and the moon and the sun, spanning centuries, and yet, they cannot put them down, study them, figure out the way they move, and make predictions. Why don't they even try? What do they luck? Would that be education, or proper understanding? For people who try to understand how the world works they put way too little effort on it.
While the FE model for the moon cannot make predications they have adopted the ancient Saros Cycle method of making predications of lunar eclipses: https://wiki.tfes.org/Astronomical_Prediction_Based_on_Patterns#The_Eclipses
Well, now you have several problems ahead of you.
a. Saros cycles do not predict the duration of the eclipse to the second.
b. Saros cycles cannot predict the path of totality.
c. There are multiple ongoing Saros cycles and you cannot know when a new Saros cycles will begin.
d. A Saros Series will finally end, and there will not be any more eclipses on that cycle.
e. You have to somehow explain why the Saros cycles happen, since you adopted them.
Good luck.
