Question: Is there a breaking point in MF?

some people i know think there is , i say no there isnt but thats just me. i was wondering what other people thought? is there a breaking point in MF (like 500 is the best for something or 200 is best for other) or is it the higher the better?

There isn't a breakpoint, but there is a deminish return.
