How the heck do you determine what the contacts course is? I've read the TMA section of the manual several times to no avail.
Seems to me that you're constantly guessing on where the contact is heading within a given 180 degree arc and at what range he's at. For instance. Technically, can't all of these solutions be correct? In each one the ruler aligns with all of the bearing lines, so how the heck do you narrow it down?
