I'm not entirely sure how accurate the exposure estimator is, to be honest. It does give you the option of selecting a target signal-to-noise ratio and it works backwards from there and suggests appropriate sub-exposure duration.

I think, in general, a lot of us don't bother with that level of detail; we simply choose our sub-exposure length, be it 300 seconds, 600 seconds, and so on, and stick with it.

Thanks for the info,
