Hi - picked up a new 2017 S at the end of August and I have really enjoyed the vehicle. Its perfect for my commute and we have a solar powered charging station at my work. Been monitoring the vehicle with Leaf Spy Pro since I too delivery and in 1500 miles and less than 6 weeks its gone from 98% to 94%. That seems pretty quick. Thoughts?

Keep monitoring, but not too often.
It will drive you nuts

Regarding your unstated but presumed question:
No one knows if your results are a trend that will continue, or which of your two readings was more accurate.

Thanks. That sounds like good advice. I keep reading about problems with the 30 KWH batteries and it has me watching it closer than I probably should.

Where do you live? It's possible you're readings are not reliable and will fluctuate a lot.

If you live in a hot climate, August is a prime month for degradation. Especially if you charge it at work, in the sun and during the hottest part of the day.

SOH seems to routinely go up and down by 2-4%. I wouldn't worry too much about it. Once you get a feel for where it usually is you'll know if it has dropped down into a new low. (Say it says between 98 and 94 right now, in 6 months that might be more like between 96 and 92.)

Please add your location to your header. Local temps are the largest factor in battery degradation. Your results will be far different depending on whether you live in Phoenix or Seattle.

Your post is useless without DETAILED charging and driving habits.

Depends on how long it was sitting at the dealer's lot before delivery. 3 months in Phoenix in the summer sitting on a dealer's lot at 100% charge would explain it.

that might explain why it started at 98%. There is really not enough info here
