1. The tables are derived from the precision data at § Precision guidelines, above. As suggested there, they use a target resolution of one-tenth of the object size.
2. The tables are not perfect. Some cases will yield a precision that is different from what you would get by doing the math (including trigonometry) for that specific case. This is because it is impossible to represent all cases correctly in a usable tabular format. The tables provide the correct precision for a majority of cases. Any error should be limited to one level of precision (e.g., d° m' vs. d° m' s", or d.ddd° vs. d.dddd°), which is acceptable for the purposes of Wikipedia coordinates.
3. d.ddddd° is roughly three times more precise than d° m' s.s".
