I would take my charger to the properties but they do not have 240 volt and high amp receptacles available outside of them. I have used Chargepoint and EA in these same routes but I have had nothing but constant unreliable charging experiences. Why cant these companies just steal SC designs and reliable integrations?

Model Y full charge range

Driving at 65 MPH instead of 70 MPH will decrease your Wh/mi by ~9%, similarly extend your range. Think of it as a built in battery reserve.
I was actually thinking about that the other day. I know it’s not apples to apples (no pun intended), but if the iPhone can give a “battery health” status by simply going into the settings, there has to be some way for Tesla to do the same. I’m assuming they just don’t want to. But it could save them on having to answer people’s questions about their estimated 100% range being down 20 miles after a few weeks etc…I would love to have this instead of battery percentages and rated miles. I wonder if Tesla's API lets us access this info. Also gives me a peace of mind if my car is really losing range or not
This won't fix their neurosis and will only feed it. They look at the random number output from the GoM (Guess-o-Meter) and it becomes the only thing they focus on.
- I've had my car for 1 day and my range is... Is this normal?
- I've had my car for 1 week and my range is... and it's changed! Is this normal? WHAT'S GOING ON??!?
- I've had my car for 2 weeks and my range is... and it's changed! Is this normal? SOMETHING IS WRONG!!!
...etc...
- I've had my car for xxx weeks and my range is... and it's changed! Is this normal? ANSWER ME!!!
Just look at the number of range threads on TMC.

But they don't really answer those questions..... I suspect if you set up a service appointment with that as the ONLY thing that needs to be 'serviced', they will cancel it. But I do agree they could easily do something like that.
It’s all normal until your battery completely dies or losses 30% of original range. That is pretty much all we need to worry about it. I know it sucks but it is what it is right now with battery tech been where it is.

Can you sneak an hour or two of Level 2 charging at one of your destinations? That would give you enough of a buffer.Ugh, it is disappointing because I was hoping to use this car to commute on my 200 mile round trip properties all year round but some of these areas do not have a supercharger so I have to take my dinosaur juice sippers... I am going to wait until summer and see if the lower watt hours will help me commute to these area. I usually hit about 350-375 watt hours right now in winter. In summer I hit about 270ish watt hours. Long-range MS is looking good now
I am thinking about going ahead and buying a Lectron level 2 charger and having an electrician run a 240 volt receptacle outside. I would buy a level 1 since I have those receptacle easily available but I would not get enough of a charge by the time I leave.

Gas cars also lose range in the winter, maybe even more than EVs do. It's just a fact of life. Cars and people expend energy to maintain optimum temperatures.
I identify. Here is a graph I snipped from my Tesla Fi app. I have had my Model Y for 13 months and have 19k miles. The top line (green) is the composite of the other 33 MY owners with 19k miles. That average range is 298.75 miles. Below, in blue, you see my car which is at 285.98 miles. There is one car with lower range than mine. (Tesla Fi data is pulled from your own car. It is not a guesstimate. The Tesla app and Tesla Fi agree as to my range on a full charge.)
Like you, I was truly worried about this much degradation so fast. I hope it stabilizes (as it seems to be doing.)
But, I am in a very different situation than you. I live in a very hot climate - today in South Texas it is 85 degrees. Strangely, my dip began last March when the temperatures began to get back to summer-time norms of 100 degrees. I also don't have a long commute. But, I don't think your car is out of the norm.
Thank you very for the great information! Now I am a little less worried knowing this seems to be the trend. Hopefully the lower watt hours in the summer time can help me make my longer commutes! Also nice to see a McAllen Tesla owner! Was their this Thanksgiving, had a blast going to Starbase, South Padre Island, and Reynosa!
I used to worry about this as well. You can imagine how I felt about my last place rank before the last bump back up. All of the various tricks to "recalibrate" the BMS seem very temporary. The big bump up at the end of my graph just happened for some reason unbeknownst to me.
Wow! That is quite a bump! Like you, I discovered all the "recalibration" gimmicks are just that - gimmicks.
To paraphrase a great movie: "How I Learned to Stop Worrying and Love the Battery Degradation."
I'm curious if the lower range could mean that you are just using seat heater more.
That wouldn't really make much difference. In fact, during cold weather, many sources recommend using less heat and more seat and steering wheel heaters because they use much less energy than the cabin heat, even with the heat pump.

Q:
Full-charge range is based on EPA mileage x the BMS estimate for total capacity of the battery.
BMS estimate is calculated by monitoring open cell voltage if the HV battery pack when the car sleeps.
Does the open cell voltage depend on battery temp at all? Could this cause the BMS estimate to trend lower during cold spells?

Do you think the 280 miles, which is the more true number, is at 100% charge? I just charged 80% and the indication is 217 miles. Seems low to meI have a MY Performance first, the most I have ever seen is 281. I don't think the range estimates are really accurate honestly. I am at 264 now, lowest I have seen is 260. I seem to fluctuate between 270 and 260, its gone up and down in that range about 3 times. The one thing I found though, when going on long trips, the estimated range is always off by 3-5% once I get to my destination... So I think the computer is conservative by nature, which is probably good. That said, I don't believe Tesla's public numbers, 290 on a Performance would be tough, would have to be super optimal conditions. I think 280 is more likely the true number. At the end of the day though, you can control this yourself some by not pushing the fun pedal as much
I think the EPA range estimate assumes 238 Wh/mi or similar; nearly impossible to achieve if you use the AC or the heat in winter.
I live in Maryland, my lifetime average is 268 Wh/mi (currently getting around 280 Wh/mi.) Estimated range at 100% is around 270 miles, been that way since new.
