I am very wary of the concept of diminishing returns for 2 reasons:
1. you restrict your exposure options without any consideration of the system design - scary
2. planetary imagers happily use 10,000 frames and up - each frame helps, even though any individual one could be left out with no practical effect

20 minutes seems about right actually, I am yet to experiment too much at a dark site. I have to admit being able to expose out to 30 minutes now successfully has really helped with narrowband imaging.
I guess the thing about diminishing returns is you still get a return, planetary images usually use more frames out of convenience I think. If I could somehow capture 10000 20 minute subs at 50fps I would too
