Icon,
Thanks - a nice selection.
It would be great if you could open the course for ranked rounds and for country club tourneys. As suggested, you could index the scores once you see how the holes play on average, in order to obtain a par-72 equivalent.
For averages, you could also weight the Best of Par 3s less heavily than the full-length courses. You would not have to explain this to us in detail since the system for calculating averages is officially opaque anyway.
There are various reasons peeps are not eager to play long practice rounds.
You could also make course awards for Best of Par 3's, using the raw scores but adjusted appropriately, thus the Diamond award could be for a 43 instead of a 57.
