Clarify?
Simple. My Vauxhaull Firenza was apec'd at -1 degree camber. I think
it was actually closer to -1.5 Had NO tire wear issues with the
oversized tires installed on it for over 7 years

A Renault R16 was specc'd at +1 to -3.66
If it was set at +1 on trhe left and -3.66 on the right it would
"technically" be within spec, but would be turning very tight tight
turns as soon as you took your hands off the wheel.
Properly set up at about -2 on each side, it would corner like a
fiend, carving corners like a knife, and holding on to the road as if
it had claws.
