32 points correspond to an accuracy of approx. 11 degrees. I guess 10 degrees is close enough and should be easily realized just by rounding the number
The best thing for the distance would be a distance-dependent accuracy. But I guess that's difficult (more accurate when closer). I think an experienced officer could estimate the distance up to 1km if the ship is not too far away (again could be done by just rounding to 1000m

). Here is an old discussion about the issue:
