Question Eibach Prokit Spring Weight Question

I have a question on the stock sportline springs vs eibach prokit sport sprinss. Looks like the spring weights are quite close to stock when not compressed. Am I reading that right? See below:

http://performance-suspension.eibach...012-13_pro-kit


FRONT:
OE rate: 29 N/mm (160 lbs/in)
Pro-Kit rate: 28-54 N/mm (159-310 lbs/in)


REAR:
OE rate: 85 N/mm (485 lbs/in)
Pro-Kit rate: 86-104 N/mm (491-594 lbs/in)


Does that mean the pro kit rate of 159 lb/in is same as stock with the 160 lb/in rate when not compressed? And when compressed, pro kit is 310 lb/in vs just the 160 lb/in. A bit confusing...

H&R are also progressive. Eibach will most likely give you a better ride over the H&R, but then also less sporty.
