I think that you folks should stop worrying about SOH - on a BRAND NEW 2016, worrying about your capacity is premature, and in fact silly... At 300, or even 1000 miles, the car has not even begun to acclimate itself... The battery needs ALOT of charges AND deep discharges (30-40%) in a short amount of time for the battery to come to true working capacity... If you only drive 3-5 miles daily, you have not even begun to use the capacity of the car and the battery.
If you only drive short distances and charge the battery every 5-10 days, then the battery is suffering from lack of use, similar to muscle tone deterioration when you do not exercise. If you are a short distance driver, just drive the car, and don't obsess about your Leafspy... I think we have too many ways to measure things today, and we love to obsess on things - like how our children are developing, or all the specs of all of our crap we buy..
PS - Just to give you an idea, I have a 2015 since new, with 35K miles on it. I drive the pants off of that car, and the SOH is still at 99.5%.... This weekend, I drove it on a 250 mile trip in one day, with many charges, and today, my GOM (at 100%) is 130 miles, better than when it was new....
