Interesting thought Mick, have spent many hours finding out the answer.
And the answer is...there isn't one, well not a definitive one anyway.
One way of looking at it is considering SNR.
A bright target (Orion) has a good SNR so you can get away with say, 20 or 30 subs.
A feint galaxy with low SNR you could take 100 subs and still be pulling in information.
For me it's a case of 'suck it and see'...
