The relationship is not linear.

In fact, the mathematics says that. It doesn't explain how to
accomplish it, though <g>.

There have been some experiments with high-energy particles which are
nicely explained by assuming time flowed backward for those particles.
I haven't tried to keep up with such things for years, but I suspect
that may be a mathematical convenience like the square root of
negative numbers, which violates "common sense" like relativistic
effects do, but is invaluable in practical things like electronic
engineering.
