Right off the batt, I would think that a distance in the vicinity of 90 degrees is close to ideal for lunars because that configuration seems the one for which closure rate is maximum (as a positive or negative value) for a given set of Moon & Body declinations.
However we should include the "retardation" effect earlier mentioned by George Huxtable (peace be upon him), which - in my memories at least - is a diurnal effect.
I am sure that Frank will tell you more but it should be pretty much in line with the above. If not, I am eager to learn. :-)
