If you are curious about your numbers for internal consumption constant and battery gauge rated miles “ticks” you can fairly easily calculate this without driving.
To calculate your increment, go to the energy app, and look at the average consumption in miles and projected range in Wh/mi.
Multiply the two to get a number in Wh that’s an estimate of energy left in your pack. Divide that by the rated miles on your display (ideal on an S would be different, check your display settings). This should give you a number, C, slightly lower than where the “rated” line is in the energy app.
If you repeat this 3 or 6 times (for last 5, 10, 30mi and 10, 25, 50km) you’ll get 6 different numbers that are pretty close to each other (x 1.609344 to get Wh/mi from Wh/km). If you average all 6 numbers I think it should be pretty close to a round number, like for the 3, which is 219, 234, and 245 for SR+, LR RWD, AWD.
I had two historical examples captured in photos, and ran the beginning and end of my commute home today. All came out to 319 or 320 Wh/mile, like this one:
Except the bottom of Mt Washington, when I'd been regening down the mountain for 8 miles:
That shows 328 Wh/mile. Or more likely, that shows that at the same 319/320 the car is otherwise running it should have been showing 172/173 miles instead of 168...
Then to get the ticks that rated miles normally update at ...
If you take that internal constant consumption number, C, and do: 100 Wh / C, you will get a number in miles that your display will tend to always tick down at (e.g. 0.48). Oh, actually you have to cut a percentage off of C ... seems to be aprox 4.5%. So multiply the answer above by 1.047. This might be due to factoring in losses in/out of the battery and/or some other shenanigans going on with the energy buffer.
I don't understand what you're trying to say here - I can do that math easily enough (0.313 or 0.328) but I don't know what this number is supposed to represent or how I'm expected to use it.
