Unfortunately I don't have anything on hand.
Your best bet would be to maybe watch some of the stream of each of the games, and maybe the par score will be mentioned:
I can tell you exactly the method we use to set the scores. We'll take all the scoring sheets from the Women's Championship and the National Championship, find out the average of those game scores, then adjust that to '5 ball' averages for the games that were played on 3 ball.
We usually end up picking a score that's somewhere between the 3 and 5 ball average, with the goal being Par 4's for all 9 holes.
After round 1 if we notice any bottlenecks due to TIME, we'll adjust scores down to try to reduce those bottlenecks. Sometimes the games that were bottlenecks weren't about the par scores being too hard, it ended up being more about the scores taking far too long to achieve.
