Did everybody reading these documents just skip past the testing methods guide? In the section from the 10/1 application for the original 2022 LR AWD MY certification, Tesla says to test battery current on HV cable extension cable under rear seat.
For the new 2022 AWD MY they show lifting the car and measuring the rear motor output, front motor output and heat pump output. Maybe the single cable under the front seat wasn't providing the proper measurements and led to inaccurate results? Also of note, the pictures of the DCDC output HV Cable was changed between the two revisions.

It looks like the large HV extension cable under the rear seat has been replaced. Also, this looks different under the seat, the black brace to the left of the opening in the picture below do not appear to be present in the first picture above. It also appears the show the seat bottom as tilting up as opposed to having to be pulled off with the current 2170 design. If the floor is solid, there is no reason to need to lift the seat off to access components underneath it. Are these the first views of the structural pack? Anyone care to go to https://dis.epa.gov/otaqpub/display_file.jsp?docid=54971&flag=1 and on page 19 (the view above) and try to zoom in on the part number tag "A" and clean it up to see what it says? It looks suspiciously like the battery label on the front of the current packs. I am not famliar with this view of the current Model Y. Anyone have a similar picture from a 2020 or 2021 MY with the rear tray removed?
In a leaked manual it mentions the structural pack having slightly different lift points. The picture in the application looks similar to the one in the manual so maybe it didn't change all that much in the final production version? That language is missing from the current online manual.
Also, the 1/27 report was tested at Kato while the 2/23 was tested at the National Vehicle and Fuel Emissions Laboratory. Mileage was slightly lower at the latter testing site but required less energy to recharge.
