Exactly. It’s like an article I saw about some new internet tech that was “X times faster than broadband”. Broadband is a type of transmission using multiple frequency carrier waves to transmit data. It ain’t a speed.

Wh/kg or yes maybe volume Wh/cm^3…

The only other thing I’d care about it charge speed. Maybe it doesn’t last as long but I can fully charge in 10 seconds? Yeah I’m interested. Hell I’ve never had a car yet get the estimated miles per gallon on the sticker. It’s all bistromathics as far as I’m concerned.
