The issue is that the charge behaviour of 10-80, 20-70, etc. is specific to lithium Ion batteries. Other chemistries have different properties, different charge curves. The only universally applicable standard that isn't cherry picked to look specifically good, is 0-100. Sure it won't help real world expectations, or help fuel brained people understand how long they'd really spend at a charger. For that you need to know more specifcs about your car. But it's an important benchmark to compair different models and tech. And should be required on the window sticker and ads. Requiring 0-100 times won't preclude other cherry picked numbers from being shown also. Requiring one will be enough to ensure both are shown.
