The current sense circuit in Black Jaguar is quite accurate in the higher current range. Unfortunately you get the +/- 1A and +/- 2A thing going on in the lower ranges. This is on our list of things that need improvement.
Gray Jaguar is rated at +/- 1A typically. Like Black Jag, it should improve at higher currents.

Thank you!
For some reason I hadn't seen it there before.
I see it also says "measurement resolution: 10 bits". Does this refer to the ADC on the ARM? Is the +/- 1A resolution the accuracy of the sensor itself?
