The deviations you are reporting are way too high though. 5-10 degrees is still usable but beyond that there is something wrong. Normally the deviation is about 2 degrees.
If you get a chance.. next time, please open the calibration display with the 3d plot of the compass readings. If you can show this while doing the rotation it will reveal a lot. If you can ensure all of the points fall on the sphere for example.
As for a different location, you would not need to remove the sensors from the box, only to move the raspberry, as I suspect maybe something is near it that causes distortions.. this is possible.
