Another out-of-bounds question

[Thom]

Since having the "T" called on the girl stepping OB from the lane, the rule now fascinates me. We have a baseline in-bounds play in which the in-bounder hesitates for a 3 count after throwing the ball in before she enters the floor. As you might guess, she is often open for the return pass and shot. Under the rule (delay in re-entering the floor) would this be considered a " delay in re-entering the floor to gain an unfair advantage"? I've never had it called but I certainly don't want it to rear it's ugly head at a bad time.
