Something wrong with my mph/rate of charge at supercharger?

I happened to visit the new 135kw Ardmore Ok supercharger today and arrived with a little less than 30% SOC.

During the visit I had 3 other cars (we were all on different superchargers (1,2,3)). Despite seeing 373V/155A at a peak I never saw a "mph" rate above 196mph, and it was often less even far short of the taper. I have noted in the past seeing a "mph" rate approaching as high as 290mph at other superchargers on my car.

Thinking I may have been on a weak charger, I swapped with one of the other guys (moving from 3 to 1) and still saw identical numbers charging my car.

The other guys at similar SOC were seeing 270-290mph. All were 85, one a year older than mine, one almost brand new.

Anyone have any idea why my effective charging speed (mph) has diminished in spite of what I observed others getting today under identical (time, temp, SOC, V&A) conditions?

Thanks

Upon digging around, I found an old screen capture that showed significant higher amperage, which must explain the difference.

This assumes, by the way, that you're in a stall with no car in the other paired connection (e.g., you parked in 3A and there's not a car charging in 3B). If not, you were sharing current with another car that was charging.

Yes. Granted a brand new 135kW supercharger. I happened to have visibletesla on at home and it shows ramping right up to 196mph. After about 15 minutes at 50% I moved over to stall 1 and saw the same thing but then the rate almost immediately started ramping down. I was plugged in for over an hour.
