Kyle,
I'll give it a shot in hopes that it helps it stick in my brain.
Classes are divided into two groups.
NATCH Classes - Regular, Jumpers & Chances
Games Classes - Tunnelers, Touch-N-Go,Weavers, Hoopers, Barrelers & Gamblers (this last one has jumps and will likely move to the NATCH group sometime in the future (over a year likely))
You can't offer 3 Rds of anything per day.
You can only offer up to 4 Rds of NATCH Classes per day. The remainder must come from the Games group.
3 Types of Trials - Standard, Double Run or Mixed
Standard Format per day - 2 Rds of Regular (It would reverse between Rds 1 & 2, with different course 2nd day), 1 Rd ea. anything else. Maximum of 7 Rds per day.
Double Run Format per day - Everything is built and walked once, run twice if offered more than once. 2nd Day Regular would be the reverse of 1st day. If offered, 2 Rds Jumpers would run one day and 2 rds Chances the other, as you are limited to 4 Rds of NATCH Classes per day. Anything else would come from the Games group. Maximum of 8 Rds per day.
Mixed Format per day - You could offer 2 Rds of Regular, with the 2nd being the reverse of the 1st. There would be a totally new Regular course on the 2nd day, which would reverse as well if offered twice. You could then do double run on anything else you are offering 2 of. Max of 7 Rds per day.
New premium will be required to reflect which rounds are being run in which fashion.
If I missed anything, hopefully someone can add or correct.
Dave
