Swift get away with it because they changed the metallurgy of their steel, rather than sticking with the common-place SAE 9254 or 9254V, so their steel can hold more compressive forces compared to the same weight of steel used by another brand.
I am going to try testing a Titanium spring as well, but due to the cost of them, not as easy to get hold of.
What determines the rate is the overall mass of steel, not how many coils there are (according to the Swift technician). Obviously on a linear spring, the coils need to be evenly spaced (regardless whether they are straight or barrel).
