I was too lazy to go back and edit after that post, got pulled into a work call, so I was waiting for somebody to pick up on that typo.It's N2O, not that it's that important though. I was very interested in hotrods in my youth.

Air density plays VERY little roll at speeds up to 60mph.What was the ambient temperature for each run? Cooler air is better for an ICE providing optimal fuel/air ratio. For an EV hotter, less dense air is better for performance, right?
Very true... drag is a v^2 term. I'm not sure what the frontal area of a MY is, but I got bored and ran the numbers...I think you meant role but in this case roll works too.
That car is an anomaly. I've never seen any other LR Y run faster than 4.6s stock. Owner most likely had a 980 motor and didn't realize it.
Apparently some kids race now by taking their cell phones out and run the speed-test app to see who has the fastest data rate.
Looking forward to seeing your latest numbers...I bought Scan My Tesla. I'll need to plug it in when I get time. I'd like to collect more data to have a better understanding of what really makes a difference for my car. I wanted to weigh it today but huge line of trucks so passed on that.
I have one more chance to do some runs tomorrow. I am charging it up again and making sure everything is preconditioned to see if it makes a difference or not. The improvement of the boost was definitely worth doing.
Today I tried something different. I setup my car to charge to 90% and then went out to make some runs. I posted my best time... drum roll... wait for it. A 4.32. Wow! A whopping 0.03 seconds faster than my previous best but with about 15-20% more charge and fresh off a charging session.
I honestly don't know how I feel about that at the moment. I don't know if I am disappointed that it didn't run a lot quicker or happy that even at about a 70% SOC it is still running about the same. Even at 60%, I am off only a bit over a tenth of a second off my best run so far. So basically from about 60 cold battery pack to 90% warm batteries back. My times only varied about 0.1 seconds.
One thing different this time though was the consistency of the runs. I banged off 3 runs that were within .03 seconds of each other. That is the consistency I expected earlier. I also had a pretty good 1/4 mile going until I had to get off the accelerator. It was on track to be somewhere in the 12.5 range. As it was, even letting off I ran a 12.60 flat.
I'll post the runs later when I have a chance. There was an issue with Dragy and it wouldn't connect to my phone. Their tech support said to uninstall and reinstall the app. So I did this just before I went out to run today and when I did this, it deleted all my previous runs. I am pretty pissed. Not to mention there is still an issue connecting. It says it isn't but it finally does. I'll be starting over to build my data but at least I have some previous baseline runs before AB.
As some others have said and I agree, it is quite possible that the extra row of seats is costing you the 0.13 seconds. I had a 2022 MYLR and clocked it regularly at 4.79s without rollout. My current MYP is doing something similar to your MYLR in that it does not seem to get down to 3.5s. Rather, it has been getting 3.68 and higher. The best 1-foot rollout time was 3.47s.Here are the additional runs.
