Some of the Quality of Service levels are mutually exclusive, others can be combined. Some introduce a natural order of "quality", that can be used to
decide if a reported value is has a higher quality, and thus can overwrite an existing value of lesser quality:
ms < ms+s0 < pr < pr+so < ae < ae+so < me < me+so < mr < mr+so < ar < ar+so < so < iv < iv+so < ic < ic+so
`ms` < `ms+so` < `pr` < `pr+so` < `ae` < `ae+so` < `me` < `me+so` < `mr` < `mr+so` < `ar` < `ar+so` < `so` < `iv` < `iv+so` < `ic` < `ic+so`
