How accurate is the spring calculator on the race tech website? It says I need a 5.2 spring (which I now have) but when I go to set my sag the spring is completely loose and still only at 98 mm sag. Is there a better way to figure out what spring I need?
My opinion, use it as a "guide" and not gospel in stone. Make sure you know what stock springs came on the bike from the factory, compare that to the RT guide information, check around with other reputable suspension companies, and use it all to help make a decision on spring rates.

I would try the factory connection spring

I will do some checking for you. My email is chris@racetech.com, but I'll post back here.
The rate is what he'd recommend, and he said it would have 3-4mm of preload on it. On the stand he'd expect it to be just the on cusp of being loose because it has a soft top out spring and the it'll grow.
Rob's recommendation was to check to make sure chain isn't too tight or axle isn't slammed forward and that you're following correct procedure checking sag.
If you don't feel comfortable with the recommendation and the spring is still new/un-used and you'd like to swap out for a 5.0, use my email and I'll get you taken care of.
Here is a quick guide for setting sag.
Hopefully that helps! Let me know if I can be of assistance any further.
Imo, getting the right spring on these bikes is more critical than the others.

Go with what it says, and better yet, make a phone call to confirm. And don’t exaggerate your riding ability.
It was strange to me, but after a while the springs seemed to lose diameter and bind on the slide.
Put the stock back in, problem cured with the binding. Plus now I’m old and slower and the tiny bit of plushness I can get out of the worst forks ever is kind of nice. 06 KTM, but the old girl is pretty cherry, and paid for.
I’m just an off-road weekend warrior but at 250 I thought I needed something.
I did, and it was the best motorcycle accessory I ever bought, a Scott’s Damper.Viola, like a new bike.
I've used the RT calculator for a half dozen bikes in the recent past and it's worked out fine.
