I'd rather be explaining that advantage was over even though I had omitted to call "Advantage over" (in a situation where it clearly was) than go back to the infringement just because I had not called "Advantage over".
Either way you look like a dick but in one way you know you're correct.
I am still not sure if you are talking about outlier edge cases [like swallowing that fly, or when things happen in split seconds] or whether you are just routinely failing to shout advantage over, just because that's the way you like to ref it ?
You haven't really said?
If we are talking about outlier edge cases, it's a pointless conversation. I don't disagree, If a fly gets swallowed, or the pea falls out of your whistle then no rule really covers it, you recover the best you can, explain and make the decision that seems best.
If it's the way you like to ref, then I don't think it's a good way.

If you think that advantage can't end 'til you say so then do you also think that it can't exist if you don't say so?
Yes, of course!
If Red knock on, you don't blow your whistle, and you don't say anything, and you don't signal, then the players will all think that you have just missed it.
Don't tell me you play advantage without telling anyone? It must drive the players (and spectators) crazy wondering if you have spotted the offence or not.
Of course you must announce, and signal, that you are playing advantage.
