Demographic desires symbols

Did a bit of a deep dive w/r to demographic desires recently
Some of the symbols baffle me, I just have no idea what they’re supposed to mean.
The 10 primary & secondary stats are easy, a lot of the tertiary ones are as well, buuut…

  • a) utility sport (and premium / lux variants) use the same symbol twice… One of them is almost certainly towing capacity (it’s used in that context elsewhere), the other I have no idea

  • b) Muscle (+P) uses the same symbol (used for engine power) twice

  • c) Light sport (+B / P) - I have no idea what the bottom left one means

Any ideas?

I don’t know what the percent means either??

Looks like camber to me. No idea why, it’s just what I see.
