X/2+7 is like the 80-20 rule: it fits 80% of the time.

Given a travel time of X, half that time plus 7 more hours seems reasonable, until it isn't. 1 hour? Full day. 2 hours? Also a full day. 8 hours? Now were talking 2 days with an overnight expense and 80% per diem.

Math. It works.

    Do you mind explaining a little more? How do you get two days from 8 hours (8/2 + 7 = only 11 hours not 48)?

    Edit: Oh, because nobody's spending 8 hours traveling and then 11 hours at the place and then going back home without staying overnight.
