Well, up to warp 9, the formula is WF^(10/3) = multiple of C. After that, it's a hand drawn curve and was never designed to be calculated...of course, that didn't stop people from figuring it out.
Gotta love us math geeks.
(I, of course, took the easy way out, and just estimated the values along the line as I needed them, but I was with the people who developed the formulas in spirit.
