Hi Jeremy yes that is correct I will have to breakdown and purchase Vol 1 not much on downloaded versions in that aspect I am a bit of a purist. When yielding 2 possibilities where would you start a new course line? Also you mentioned you averaged your Moon sites but upon my graphing them the 21-01-40 and 21-03-22 sites I considered fliers and therefore solved 21-00-48, the mid site. Thanks much.
