Slow Supercharger charge speed, potential issue for long distance travellers.

First, the good news, Tesla cars are all over the place now, cutting down carbon footprints and saving the planet one car at a time. The bad news, as more and more cars hit the road, the limited supercharger spaces are getting stretched and charge speed can vary from one location to the next.
Back in 2019, every time I went supercharging, the starting supercharging speed (power draw) was always over 100kw if I had less than 30% of battery capacity, of course assuming the supercharging site is capable of 120kw or 150kw at the time. Fast forward to 2021, I supercharged 5 times the past two weeks, 3 times in North Brunswick route 1, once in edison nj and once in East Brunswick nj. (Btw, I live in NJ, so it may or may not apply to your locations). North Brunswick never got above 60kw in three occasions even though I had less than 30% battery left, it took 80 minutes to charge 120 miles. I was getting around 26kw consistently each visit. Edison was worst, I was getting 22kw with 20% battery life left, although there are 6 cars out of 8 spots there. I couldn't take it so I drove 20 minutes to East Brunswick and boom, 130kw power draw and I charged from 20% to 90% in 40 minutes which is what I was experiencing in the past.
I know there are variables such as battery remaining, ambient temperature, battery temperature, how many cars are sharing, etc, but one time I charged in North Brunswick NJ, there were 3 cars including mine out of 8 spots and it was 50 degrees, still got 26kw power drawn.
Bottom line, have an expectation that the fast in and out charging that people spoke of may not happen everytime, try to give yourself more time when planning a visit to a supercharging, as well as additional time to be spent when doing a road trip. Not saying it'll happen to everyone, but it's much more likely to happen today than it was even just 1 year ago.

 

You're right on the split power, hence I tried multiple times and twice not sharing any power with other cars. You're also right that maintenance may be an issue with more usage. BUT, I've supercharged dozens of times prior to pandemic (march2020), zero issues, even when sharing or splitting power with another car. I'd be getting 60kw consistently, NOT 26kw. You're also right that preconditioning the battery prior to supercharging is important, which I do every time. The slow supercharging speed I mentioned in Edison NJ, I drove 30 minutes prior to arrival with 20% battery capacity, I got 22kw.
Again, never had an issue prior to the pandemic, but 4 times out of 5 this year I got slow charging...

 

No, not aware of batterygate nor chargegate. Can you please elaborate?

 

I already scheduled service, though I'm not sure that's why I'm here to share and ask for opinions.
That last time I supercharged, I got 130kw initially and 170 miles in 40 minutes.

 

True, but 50F ambient temperature, Supercharge station set as destination, 15 minutes drive to supercharging station. 30% battery life. 26kw power draw, 3 cars out of 8 possible stalls, no other cars sharing with me, took 80 minutes to charge 120 miles.

I don't pay much attention to regen bar, but I could easily do one pedal driving in streets/highway driving while on my way to the supercharger stations.
On Sunday, I drove 25 minutes on my way to a supercharger with destination set and battery conditioned, got 22kw power with under 20% battery life. I said screw it, drove another 15 minutes to another supercharger, boom, 140kw, got 190 miles of range in 50 minutes.
