If you have called the following group through and you then find your ball you should really stand aside and let them go on - etiquette. You shouldn't recall your 'wave through' - though we should be pragmatic and consider whether you waiting for them actually slows this up more than if you just play on and explain to them at some point. Even if you play on however I believe it is still courtesy to stand aside as soon as they are ready to play.
I agree - I was just playing devil's advocate to prove a point!
