If it helps you to think of it as "Monday/Thursday" please do that instead.
There is no earthly way I could accumulate statistics on 67, 68, 69, 70, etc hours between intercourse rounds!!!! There is no magic to the 72 hours, I just want you to have sex in a pattern so the attempts fall O-3 and O Day OR O-4 and O-1 OR O-5 and O-2. But that is a lot of explaining!!! so I shorten it to e4d, and people get confused, so I say 72 hours, but that's only an illustration and not meant as strict directions.
