I'm confused. Aren't the bottom measurements absolute? That's what I was referring to. -1.5 means exactly -1.5.
Think about your measured caster angle. A car with a longer/shorter wheel base would have a different tangent from the wheel reflector to the alignment sensor, therefore throwing off your caster angle number. It has to be compared to a known "normal" alignment setting.
Edit: Regardless of it being absolute or relative, the OP needs to have it realigned by someone who knows what they're doing and can select the correct car.

That is fair. At least they got the toe in spec in the front. Rear still looks a little questionable.
