I've had very few problems with a dropped chain back in my days. we were taught to develop a feel for when the chain jumps and you could hear the noise it would make right before and like cafzali said, to look for the right time to do it. Could it be that today's jittery stealth bomber carbon frames contribute to this by amplifying every tiny little rut or bump right up the fork to "vibrate" (for lack of a better word) the derailleurs or the chain to cause this? I'm sure that shifting under full force puts undue strain on the components. One thing I disagree with is that the process is the same. Manually shifting (like with down tube shifters) is a much slower process where the chain is advanced more gradually over to the next cog versus modern shifters that pop the chain over immediately.
