FWIW it is not so

I thought so too. (EDIT: sorry!, on posting I see that I misunderstood your words. They do take progressively more weight

... More of the same unit of weight compresses the spring as much as the last unit of weight

I'll leave the rest of the post here anyway

) Springs with identical windings have the same spring rate throughout (except at the VERY end of compression!, out of bounds really). Notice that for linear springs the spring rate is given in kg per mm, as in how many kg's worth of pressure it takes to compress the spring 1 mm

- And that there's no measure of compression given.
Also cutting a spring makes it stiffer

I thought the inverse
Here's a spanner in the works too:
Spring Rate Selection
Sag isn't everything, can do A LOT in the valving, speed and terrain are the main things to tune the 'spension for.
Edit: That's a lot of smileys!

I'll blame the coffee!
