28.3 - range reduced on 100D's?

[Magellan55]

I've seen the posts on Tesla reducing the range on older / S85 cars, but after installing 28.3 about 2 weeks ago on my June 2018 build 100D, my range dropped almost 10 miles. I charge to 85%, and normally that gets me 287+/-1 miles. After the latest upgrade, that's now 269. I confirmed on the charge screen that's it's still set to 85%. Anyone else experience this on a newish 100D?
