Question on the advantage clause

[wardtc]

OK, spring is just around the corner. The season is about to start. Since I am still relatively new to reffing, I wanted to screw my head on correctly about the advantage clause. I sure do appreciate your help.

In the event a defender causes a foul, the referee calls advantage, the ref should wait two -three seconds to see if the advantage develops. If it does not, say the attacker looses control of the ball, is diverted from his attack, etc, then after that two to three seconds the ref calls the original foul, and deals with the restart as normal, right?

So if it was a slight trip and the attacker looks like they are going to be able to play through it - call advantage. If right after that the attacker stumbles (as a result of the trip), the foul is called...etc.

If the attacker does play through it and five seconds later stumbles (not from the trip) then too bad. No foul called, they got the advantage, and lost it, right?

If the trip happens, the advantage is called, but the attacker just quits (thinking he should have gotten a foul, or didn't hear the advantage call) then that too is just too bad, right?

Should advantage be limited? In other words, does the use or overuse of advantage lead to problems later in the game?

Is it a good idea after allowing advantage, for the ref to have a word with the offender at the next available opportunity? Should it be a quit word, or loud enough for all to hear? If so how long is too long after (sometimes the play can go on for a while yet)?

Are there any questions I haven't asked, that I should be asking?

Thanks again for your help
