WOT is the assumption with that test. Chill allows a maximum ceiling of power delivery limiting over throttle at the same point compared to other modes making it more desirable towards efficiency.
Thats exactly my point. Its a simple remapping of the throttle. The entire Chill map equals whatever, say it was 50% of the Standard map. So just use 50% of the Standard map, and get better with your foot so you only move 3mm in Standard to get the identical response of 6mm in Chill. (actual % is what it is).
what data?
I don't believe so. I suspect that if you floor it you're getting only a percentage of the total available horsepower. ut I've not tested it personally, I only had it in Chill mode long enough to realize that the mapping is way too relaxed for my taste. Never pressed all the way down.
That' correct. The max power is reduced in Chill mode. It is very noticable if you try to pass another car and floor it and the car just doesn't accelerate as you expect it.
That makes sense, especially for something called "Chill" mode. And now I know that I'll never use it. If the sportier mode was overly sensitive and tough to manage at slower speeds then I might feel differently, but I don't find it too aggressive at all, not after a minute or so of driving. They've done an excellent job with the mapping. Still, I would never try to convince my wife to leave Chill mode because she'll never need it. Yes, these people are missing out on all the fun.
The delay in my car is well under a second. When I first set the accelerator pedal threshold to 100% then there would be a fraction of a second delay which felt just like turbo lag. Then I moved the threshold down to 90% and I don't notice a delay.
I read that in the manual of the S3XY buttons. I believe the car won't allow a sudden switch between power settings.
I didn't know there was a manual for the S3XY Buttons. I looked and still can't find it. Can you provide a link?
I wonder if the various delay times are due to hardware limitations. Because acceleration is mapped, the level of torque at the motor correlates to a specific amount of pressure on the accelerator pedal -- that's what mapping is -- but the maps/curves for Chill and Sport are not the same, so if you're pressing half-throttle in Sport then switch to Chill the car must adjust its torque to match the physical location of the pedal. I imagine there's some nuance to making this physical adjustment smoothly, and each situation will vary depending upon how the car is being driven. It's not a tough algorithm, but there's probably some math behind it, which might explain the time variations.
Acceleration is physically limited, of course, but changes in acceleration are not, except by how fast you can ramp current to the motors (which is very fast, on the order of milliseconds). If Tesla added a significant artificial limit to rapid changes in acceleration then a 2 second 0 to 60 time would be impossible. There would be a significant delay before regen kicks in when you take your foot off the pedal while you are accelerating. Likewise, no one's head would get thrown back when the driver floors it.
I think we're talking about two different things. I'm strictly referring to the transition from one mode to the other and how the car deals with that, mathematically. In theory, there could be a delay as the new mode "settles" in. I'll just put it that way.
This is not my experience when using kickdown mode or using the S3XY button to switch modes. In addition there is no advantage to significantly delaying the change in acceleration mode since the car already abounds with sudden changes in acceleration. If you have any actual experience with this or if you have a sound theoretical argument for why it would be beneficial, I'd be glad to hear it.
Again, we're not discussing this from the same angle. There is no reason for Tesla to intentionally delay the handoff, and I'm not suggesting that they're doing so. What I'm saying is that you can't simply move from one map to another immediately in every case. To do so would be dangerous.
I am a physicist. I understand what you are saying and I can tell you there is no science to it. Waving your hands and saying "science" does not intimidate me. You seem to agree that in the general case there is no benefit to limiting the change in acceleration. So it makes no sense for Tesla to go out of their way to limit the change in torque in the special case of changing acceleration modes.
You are wrong. If rapidly increasing torque were dangerous then the cars would not be able to do 0 to 60 in two seconds. These cars were designed to rapidly increase torque and acceleration. As I've told you before, they are only limited by how fast the current can be ramped in the motors. You seem to be confusing jerk with acceleration. You're intuitive understanding that a rapid change in acceleration or torque is unsafe is simply wrong.

Driving at 20 mph, the legal limit on 50% of London's roads, is good training for pedal control in Normal mode. I have yet to even try Chill. I would use it in town but for my concern that I would forget to change back when leaving town for the motorways; I am used to the car's available acceleration when required for a manoeuvre in traffic.
