This goes back to the issue of, 'Why are you doing it?'. In my situation I wasn't doing it to receive any "amount of good". I was just doing it to do my friends a small gesture. And if I could do 5 friends a small gesture, that's probably more gratifying to me than doing only 1 of my friends a small gesture.
