I know you  

don`t set much store by such calculators Milton but it may be useful

I'm not against anything.

However until you actually prove that these calculations are even vaguely meaningful by imaging one of these targets with their suggested exposures, your just wasting your time.

Hypothetical imaging doesn't put photons on the CCD. You only gain practical experience by going out and shooting targets in a methodical fashion, with plenty of notes so that you don't repeat the same mistakes over and over and over again.

HTH..
