VGA Theory… hmmm

Has anyone out there played with VGA from scratch.. im trying to figure out the basic timing…

640 x 480 in my mind is:

640 + 1(HSYNC) = 641 * 480 (VSYNC) = 307,680-Cycles= 1 SCREEN PASS (1hz)

307,680-Cycles = 1hz screen rate
307,680 * 60 = 18,460,800-Cycles= 60hz screen rate

0.000,000,054,168,833 or 54.169ns clock…

does anyone figure this as well ?
