Static sag is dependent on rider weight and luggage so it is going to be different for all riders of different weights. Consensus however is there is too much static sag given the OEM spring rates. I'm 150 lbs and had 47 mm of static sag with OEM preload. That's 44% of travel when a good range is 30 to 33% of travel. Because I am light and always ride solo the OEM spring rate was OK for me and with 16 mm of additional preload I got static sag to 36mm or 33%.
