Danny, I'm not sure there is an entire stop between F30/31 and F300 (then, neither from F200). I've just seen some iso1600 in M size from F300 that is ALMOST comparable to my F30/31 shots.
I try to hazard half a stop, nothing more because I see the details inside some iso1600 pic that I don't see in some F31 photo (which is, on the other side, cleaner -NR-). Maybe I'm wrong but this is my feeling as far now.
