Sensor Offset Question

How far from center of gravity does it become relevant to set the INS Offset? For GPS, I’ve set -7cm on the Y axis for the sake of RTK accuracy. IMU’s are 3cm forward on the X but I haven’t made those settings change yet.

Not very critical unless you’ve got a very large aircraft, maybe you’d do it if the flightcontroller was 20cm or more from the centre - bit of a guess though.
