@MichaelPorter
The subtitle reads "energy flows... on a common scale."

I understand the maths and you're explaining it well - thanks! But the figure is still a little confusing that one scenario gets 11% braking returns and the other 19%. Might just have been better to leave that bit off.

@MichaelPorter @yugthebug @Natasha_Jay so the common scale in the subtitle is wheels moving? Definitely a bit of a mind-twister! Possibly because the flow implies remaining.

Are you ok? Blink twice for help.
