We were all more naive a decade ago. We hoped that a single application of drugs would result in a dramatic benefit. We now understand it's much more complicated than that. People are optimistic but we're not expecting home runs. Right now, people would be happy with a series of singles and doubles. (Franck Rauscher, the director of the NCI, 1985)
I think a home run is going all around the baseball diamond (which consists on reaching the fourth base) and a single is the first base and a double is the second base. Is my understanding correct or is it more than that? Would a home run count in points four times reaching a single and twice reaching a double?
