Maxred & peacock, it doesn't matter what was briefed, if you have lost sight of the other aircraft you don't keep pulling on the stick... The contract generally is n+1 avoids n avoids 4 avoids 3 avoids 2 avoids 1.... and then after that lead does his best to fly smooth and predictable.
Now, I do see your point, but not sure that you can remain visual with the guy in front throughout the break. Once he has broken you keep looking out the front, wait for the appropriate delay, then fly the same briefed profile. It is only then that you re-aquire the guy in front - expecting him to be on the horizon a good few hundred yards ahead. If you don't see him, are you immediately going to break out or call "lost visual" or simply keep looking until you eventually find him? Not always a 'comfy' position to be in, but been there many-a-time so can easily relate to it.
