Such minor changes would be visually almost identical to right now, but actually make the app useful, I really can't understand any resistance to it. the clean look doesn't change, but it becomes useful, how's this bad in any way?
And I don't understand how someone would care if the regen is at 23.5kW or 27.7kW. A quick glance to the IC can give you a ballpark of how much your regen is limited, without requiring extra tick marks. How are you going to adjust your driving knowing you have an extra 4kW or regen? You wont. And you can eyeball if you have an extra 15kW of regen from the tic marks that are there now.
Some people have the perspective of "more is better". Which is fine for them. But it does nothing for me. Lots of complaining and the clock is back on the IC. Do I like it on the IC? eh, no biggie. Lots of complaining and the temp moved from the 17" to the IC. Do I like it on the IC? Nope. Not because it clutters the look, but because I preferred it on the 17" display. Why did it get changes? In part due to the vocal members on TMC.
As to your question: I'm fine with adding faint grid lines to the middle of that circle (energy history?), but I don't need to see lines with numbers telling me if it's 5 miles, 10 miles, 15miles, etc. I can figure it out on my own. As to the outside of the circle, I think the resolution is good enough. I don't need more numbers. If you add tic lines, you know someone is going to complain that the tic marks now need numbers next to them because they wont understand what the tic marks represent. And yes, that would clutter the look.
What would be ideal? Make it customization. So that the power users can get the resolution in whatever numbers they want (1kW tics, 5kW tics, 15kW tics, 25kW tics, 50kW tics, etc.). I don't see that happening in the near future though.
In either case, this is likely a moot discussion. Tesla leaked the v7.1 (or what we assume is the v7.1) energy meter, and it's completely redesigned.
