The time a task can slip without delaying any task that immediately follows it.
That inspection has three days of free float, so a short delay won't touch its successor.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
