Hi Roger: I've been using your new DC macro that includes the Bailey Points. I noticed however that you modified an older version of Fer's analemmatic macro that only shows hour point time increments. Your modified DC macro would be much more useful if you would include time points options for 1/2 hrs, 1/4 hrs, 1/6 hrs as Fer does in his updated version. (see attachment).
Just a suggestion!
