Some thoughts:
My guidance to measurers is that for courses 10K or less, the split descriptions should be on the course map.
That being said, there is no requirement for splits to be on the map at all. Just points that define the course. Unless the split points are certified, they're for information only.
If the split points are on separate sheets, and the measurer wants them to be posted, then the sheets should come to the certifier already reduced so that everything fits on 8.5" x 11". I shudder to think how something reduced to much less than 50% would scan.
I am also less than concerned about having everything posted so that more than one organization can host a race on the same course. If they want to use the course, let them contact the organization that originally went through the time, effort, and expense to design the course and have it measured and certified.
