If anyone wants to check out the scores and ratings from last years tourney go here: http://ratings.blazinglite.com/searchEvent.php
and search for RCF Club Championships (2012). Last year the Saturday round at Endicott was 27 holes, so that is why the scores are so high.
I was also doing some research for all Members that have a rating (http://ratings.blazinglite.com/reports.php
All Ranked with Average) and it shows that there are 339 players between STL and SCC with a rating heading into this tourney, 284 that are STL only.
If we want to use the ratings for this tourney, I would recommend using the following breakdown based off the 284 STL members rankings:
9.80 and above (39 members) - Recommend playing Open
9.25-9.79+ (56 members) - Advanced
8.80-9.24 (66 members) - Intermediate
8.25-8.79 (68 members) - Recreational
8.24 and below (55 members) - Novice/Beginner
I think this would make a decent spread while having like skilled people playing together.
