2 doses appears cheap on the surface but its not that easy for every one to totally re-gather cattle, especially young calves, multiple times, in that short of a window. There is a cost associated with all that for a lot of people, also.
The odds of our cows letting us re-catch them, with with young calves, 2 weeks later, is slim to none.
