I'll Decide ...
So here is how it should work. The team should be in a better position compared to a free kick (benefits is the word used in law) for you to play advantage. If you are not sure, you wait a few seconds to see. So if you played advantage that means they were in a better position, if they stuffed up after that, then its their fault and by bringing the ball back you are giving them two bites at the cherry.
In other words, playing advantage doesn't mean you are waiting to see if they are better off, it means they are already better off.
I agree with that logic too. That train of thought also (I think) lays waste to the notion that you can't/shouldn't play advantage unless it's in the attacking third of the field. A quick break from inside your own half is often more advantageous to you than a free kick (with the opposition having time to pull everybody back defensively) would be. Conversely, having a free kick (with a chance for a measured and unhurried shot at goal) just outside the penalty area is often better for you than allowing open play to run and you flap and fluff the chance the ref has given you by playing "advantage". Each situation is different.
