I can see how coiling steel rod into springs of a specific height at a certain rate of resistance could be less than a perfect science. I see the numbers as general and within an inch as an accepted variance. I imagine they have a way to test the rate and match springs in pairs, but just my hunch. Heck, for years people have been calling 2 1/2" drop spindles with 2" drop coils a 4" drop when the numbers add up to 4 1/2". I've used drop springs on 2wds and lift springs on 4wds and just assumed it did what they said, never have measured.
