Without attempting to reference any particular races in the near future or recent past, I'm scratching my head and wondering about the splitting of courses that are listed in the current OUSA rules
. At least in part because I graduated to a new age class this year and am still trying to get my bearings.
My recollection is that it first began back when there were so many red course runners that it conveniently solved the problem of needing an extra-long start window just to accommodate that 1 course. Over time those folks have aged and moved on to shorter courses and the solution has followed them as they went.
My question at this point is: are there other reasons organizers would need to diverge from the standard course structure and create additional courses other than to manage the start window?
Regarding rule A.11.2.9 If desired, age divisions may be further divided into additional classes by course difficulty and skill level.
I might be misunderstanding but I'm assuming this is saying that it's ok to divide classes by adding e.g. 21E courses/classes, or even B or S categories, which is different from splitting e.g. a Red course into X/Y to keep the start window under control.
