Why is estimated miles = 0, and ideal = rated miles in your first example?

because the Model 3 does not have the ideal conditions showing, unlike S and X.
To avoid confusion, i assume tesla went away without that value.
All these numbers just pulled directly from the log from Tesla's API server.

On the model S/X:
Estimated is based on the historical consumption the past 30 miles.
Rated = is self explanatory (based on Car's rated Wh/mi - 300Wh/mi for MS, 230Wh/mi for M3 vs rated battery kWh)
Ideal = also self explanatory (under ideal climate, battery temperature and speed)
Someone please correct me if i'm missing something.
I'm not so concerned about 100% value, as that may just be a calibration thing. I am more interested in monitoring any degradation. After 7 months and over 5k miles, it still shows 71.7 kWh battery pack capacity, so I will keep monitoring it...

Really similar, mine is between 217-219. Shouldn’t the battery capacity be 75 kWh and not 71.X kWh? What am I missing?

2014 Model S60, 60,300 miles with a lifetime 319kWh/m average. I currently get a very disappointing 150 rated miles @ 90% and 167 for a full range charge. Nearly 20% degradation and the service center says this is normal and within expected limits and reminded me degradation wasn't included in the 8yr 125,000 mile warranty. All of the data I've seen aggregated from others make it seem like I'm an outlier and that something is wrong even though the SC says my battery is "healthy"
Brandon, It doesn't look like you will hit the 125k for the warranty but I don't think the pack will last 8 years. Look at the bright side if you like your car in a few years you could get a 75 pack put in for free. Time will tell if the 18650 battery can last 8 years or more with the current draw we put them through. There is a lot of 18650 batteries in your pack not to have one of them go bad in 8 years. As long as you have enough mileage to do your daily commutes all good for now.
Sorry to hear that your battery degradation and service center experience have been so disappointing. May I ask to which SOC you charge your car daily?
I have a 2014 S 60 that was down to 154 rated miles at 100%. I had been keeping my SOC routinely between 55-75%. The SC and NA Tesla Service gave me the same "healthy" reports, but they also suggested I charge to 85-90% daily. I've been doing that for the past year and my 90% SOC is up to 165 miles. Best wishes.
For the first ~2 years of ownership I charged to 80% nightly and the last 2 I've charged to 90% and my rated miles at each have steadily dropped. They gave me the advice to do the charge to 100% and drive it below 20% three straight times so I'm doing that now.
With the thread being so long, I may had missed seeing this. For anyone else that may had, Teslafi now offers a
Battery Degradation Report
Battery Degradation Report
So I've done the 3 charges to 100% down below 20% and my 90% and 100% rated miles are exactly the same. The alarming thing to me, assuming I'm not missing something, is that on my last charge to 100% I drove until the battery was ~5% and my trip section shows that in that 95% battery usage I went 126.4 miles with a 309 Wh/mi average and total energy used was 39.1kWh. I know my 60kWh battery is not 100% usable but the fact that I only get 39.1kWh out of 95% of the battery seems to really suggest to me that something isn't right.
