How to model SUPER strong and fast characters?

DX, IQ and HT are less readily measured in real-world terms, and values in the 20-30 range are about as high as the game system copes with. DX 500 doesn't make all that much sense. Why do you feel you need numbers that high? "To be on the same scale as ST" isn't really a good reason.

The reason is that most of important characters in this universe have achieved reaction, fight and movement speed greater than mach 1. Top 10 characters have speeds in the range of mach 5-500(it's reaaaly incosistent and argueable so I just choose lower bound of mach 5-10). But still it's more than thousand Basic Speed. So I am looking for the way to model this, but GURPS don't seem to being really good at this values. This is not like I want it or not for any particular reason, I just need to match the source.
