When does travel occur?

Based on your previous posts you are immediately calling a travel, correct?

If the drop is all part of the original motion, or close enough that one can imagine such, treat it as an errant pass, and see what happens next. If the motion clearly stops, and there is a discernible pause, followed by a deliberate drop straight to the floor, it sounds like the start of a dribble to me, which means that it would be a travel.
