Preemptive Stress Fracture Time Off?

I feel bad for your situation, but at the end of the day you know your bad better than anyone else and it sounds like you've essentially answered your own question. I would suggest taking some time off and then moving to running 2-3 times a week, but really upping the x-training. Get on a program of core and lifting, stretching, swimming, biking, eating healthy. The time away from running can help you discover the smaller fine-tune aspects of running.

It's a tough call. You have to think about the fitness you'll lose if you take time off. If you're serious about training and spring racing, I'd consider just steaming through the rest of the winter.

bumping to specify my question. I'm pretty sure I'm going to take time off at this point, what I want to know is whether I can get away with something like 3 weeks off as opposed to the standard 6 plus since I've diagnosed it super early.

I had had a few sfxs in my foot. I heard everything from 8-12 weeks to wait until you have no pain as the recommended time off. I don't think there is any real consensus on the amount of rest it takes since every sfx is very different, as is the patient/victim of the sfx. If you want to be agressive, wait until you are pain free. Otherwise, your chances of being 100% after 6 weeks is pretty good.
