You're saying present the data to the certifier as 3 rides; 2 segments plus a continuous ride. I'm not sure...
If I measure a course with 2 segments, there are data for 4 rides. In your method you don't have 2 rides for each of the segments. I'm sorry, but I don't think the certifier will accept that. I've measured about 400 courses, maybe the certifier would accept the 3 measurement method from me. I doubt that a new measurer would receive the course certification.
When we measure segments, we always have 2 measurements of each segment and the ends of the segments are located and identified with the same precision (as noted in appendix D of the measurement manual, case 2) as the start and finish.
Additionally, we must agree to disagree that any ride where you "back up" is a segmented ride. If you have a continuous set of data, it is not segmented.
