Next 10mm to 30mm = 8.45 kg/mm
Next 10mm to 40mm = 8.60 kg/mm
Next 10mm to 50mm = 8.80 kg/mm
Next 10mm to 60mm = 9.50 kg/mm
Next 10mm to 70mm = 10.50 kg/mm
Next 10mm to 80mm = 12.50 kg/mm

There was no point testing after that as by then the shock would be nearly 10mm into the bump rubber so the spring wouldn't compress anymore anyway.

This totals out to be 746 kgs over 80mm of spring travel which provides us an overall spring rate of 9.3 kg/mm.

Terry today ran this past Paul Thede of Race Tech who informed him that the current P series has been recalibrated since 2010, so perhaps that needs to be taken into account?
Does that mean the P 20 they sent me for my 2014 300 exc is nfg?
