For those of you who are wondering just how fast your Model X will charge at Supercharges, I just took a road trip with my 2018 Model X and captured all my supercharging with a python program then aggregated it once I got home. This plot shows how a BTX5-A battery charges at both V2 and V3 superchargers these days. I did not see any meaningful difference between v2 and v3 chargers during this trip. This data is aggregated so there is a plus or minus 5kw variation at each data point. The charging range is 9% up to 95% and contains at least 4 samples for each charge level. The peak charging area is between 18 and 38 percent.

Model X BTX5-A Supercharging curve

I'm guessing the X-axis is actually charge percent since charge percent plots as a straight line. The battery charges much slower at higher states of charge, so there's no way the charge percent just increases at the same rate during the entire charge session.
Hmm..lot of factors in play ..you have a SR so your not seeing full peak of a V3 SuC.. also as other have mentioned SOC matters as well...in general I will agree that V3 speeds do not necessarily shorten charging duration in the big picture ..
...in my case my BTX5 batt is now limited from the BMS due miles and amount of supercharging I have done so I can’t even get V3speeds anymore ...

I have tons of data on this from our 7K mi road trip last mo and for the most part once you hit the taper in the ~40%, charge speed will be ~120 (+-10) back of SOC. Example: 50% will be between 60 to 80KW on an unpaired V2 or V3.
This is on an unthrottled RevB BTX5 so YMMV.
Selecting range mode seems to make for less optimal sessions with lower peaks. V2 charge handle rag trick is almost mandatory in hot weather if starting off with a very low SOC.

Is the standard range the X75? If so, they charge slower than the larger packs. Mine is usually limited to 75 kW or so unless it is really warmed up and at low SOC (< 20%).
Can't wait for the lease to expire in May and move up to LR with the new battery pack.

I have receipts. Hot handle causes a throttle back similar if not more severe to that of another car plugging into your circuit on a V2.I’m curious as to what speed differentials u get as I charge a lot in hot climates ..I normally don’t carry a cooler with ice but if speed differences are significant I may do now
