Is it possible to record and statistically evaluate 9-hole rounds with FORE?

Yes, it works fine.

Of course, golf is usually played over 18 holes in tournaments, but often - especially parallel to the training process - you only have time for a few holes.

But these holes can also be very helpful in determining the current situation or in controlling your own development process. Therefore, with FORE you can also record shorter rounds than 18 holes in your statistics.
