Ron, I did do this calc wrong. The distance to the moon varies about 3 percent between moon overhead and moon underfoot, whereas the distance to the sun, noon vs midnight, only varies only about one part in ten thousand, or a hundredth of a percent. Turns out the tides are more complicated than that. Looks like you did your homework. Back to Physics 101 with me... {8-[ {8^D spike
