Upgraded front springs, rear shock question

Hello all,

Decided to keep my 250r for another season, and since i'm 210 lbs and my seals were leaking a tad last year, i decided to get the seals replaced and also had .85 racetech springs installed.

my front sag i measured at around 35mm. (not sure what the preload is however)

Now, the rear shock. Racetech calculator shows the stock shock should be just about right for my weight. But i have the preload at setting 5 and my sag is still around 38mm (which i can live with). But as far as i can tell i have 0 static sag (no rider on bike). I am thinking about dropping the preload to 4 and see if i can get even 1 or 2 mm of static sag.

But my question is, how can this be? If the shock is correct for my weight, shouldn't i be able to use less preload and still get a good sag number? Or does it mean my shock is not working correctly? (i bought it used so who knows if its an actual stock shock...)

Anyways the 0 static preload is worrying me after watching countless dave moss videos :P

Any thoughts? Is it not correct that the stock shock should be right for me?
racetech:
recommended: 9.14 kg/mm
stock: 9.3 kg/mm

Also, can anyone tell me the total amount of travel that the stock shock has in mm ?

Thanks!
