Maybe they are not!! Perhaps Martin could jump in here and put the record strait.
I guess what really matters is how they perform for each of us but it would be nice to know for sure!
I could be wrong but here's what I think:
There are different linear coiled springs that for example read 200gr at 1cm compression. From those springs the are some with fewer/more winds or a smaller/bigger diameter. Although the winds are parallel to each other one spring will have for example 100gr @ 0.5cm, 200gr @ 1cm, 300gr @ 2cm and an other will have 75gr @ 0.5cm, 200gr @ 1cm, 325gr @ 2cm. So people will say one is more progressive becouse it gets harder compared to an other spring although spring rates stay linear and is something completely different than a real progressive spring with different coils.
