Great thread, Greg.
I believe this is especially relevant to EP's; a species that is well documented for it's 'shutdown' attitude once fish are released back into the water. One exception to the rule that springs to mind is Barra. On more than one occasion (sightcasting), I have caught (and seen others catch) the same fish that was released just 5 minutes prior. Having said that, the barra weren't schooling at the time. Bream are infamously finicky, yet tournies appear to catch multiple fish from one spot, even after releasing others in the same location. There must be some sort of scientific research to explain this, although I guess there is a huge amount of variables to consider? I look forward to other people's comments!
Cheers
