298 miles is my new 100% (LR RWD)

I have a LR RWD Model 3 and recently received the 5.15 update. The range did not change at all. I tried charging to 100% and it only reported 304 miles of range. I'm not particularly concerned one way or another though.
What was the outside temperature when you charged? I’ve found that if the battery is cold, like 30-35 degrees F outside while charging, it will finish charging showing a lower indicated range (about 3-5% lower) than it should. When outside temp is around 60 or higher, range is spot on. I live in NJ. LR RWD.
That does make me feel better, thanks
I was down to ~295, but a deep discharge (< 5% left) bumped it up to ~303 before it started dropping again. Have you tried a deep discharge to see how it affects the rated range?

I have only been using TeslaFi the last 2000 miles or so. LR RWD with 21k miles in less than 11 months. Battery report varies from 298-302. 5.15 didn't show any change for me either. I leave display on % for one reason not to sweat these small changes.
I think temperature has a lot to do with it though and we'll see if it pops back up in summer. Either way I'm not concerned, still very low degradation for the amount of driving and 100% charges I've done.

I've only run my battery below 20% once. Went as low as 16%. How low should I go? 5%?That does make me feel better, thanks
@Sparky4life @Swampgator Don't forget to add your graphs to:

It's simply battery degradation. Degradation supposedly happens fastest when the battery pack is new. The older the pack, the slower the degradation rate. Switch your display to show battery % instead of miles and forget about it. Here's my degradation after 43,000 miles and 16 months:

It's from TeslaFi.com Tesla Model S X 3 Data Logger
It's a paid tesla monitoring service. It's pretty cool... but it is not free after the trial period.

I already run %
But you have lost 3% after 40,000 miles. I have lost 5% after 11,000

I suspect something's not right with the update. I did a trip charge on the 10th, it was at 309 of 310 with 10 minutes remaining when I had to leave. After installing 2019.5.15 my 90% didn't go up as much as expected, so I did another trip charge which yielded 316 instead of the expected 323-324.

We'll see what happens
Did my first full charge last night, wife and I are taking a mini trip to Santa Barbara from Orange County.
Interestingly enough, charging “finished” at 305 at 4am. Then I just woke up, started charging again cause I assume I have 310 max range. Well, it’s slowly creeping up 1 mile to 310 every 1/2 hr. I’m at 308 now. But it is telling me it’s complete.
3p+ 1700 miles. I am guessing it will get up to 310 soon. Using 30amp plug.
Anyone seen this before?

Well, after a several deep discharges (<=5%), I am almost back to 310. I learned that it takes more than one deep discharge to 'reset' the BMS algorithm that estimates capacity and that discharges down to 5% are much more effective at this than discharges down to ~20% (which I tried first). In any case, I'm more convinced that this is just variation in the algorithm rather than any real physical degradation of the battery.
