I'm trying to enter scores for a round of 18 holes on a 27 hole course. How do I end the round? Looks like the app expects me to finish 27 holes.
A "round" on a course in the PDGA Course Directory is expected to be the number of holes shown in the directory in order to produce round ratings. However, that doesn't prevent you from creating a new course with a similar name that only has 18 holes where you enter the details on the 18 holes you want to include. However, no round ratings will be produced, at least in this early version of the app.
