The performance schedule for the day to that point was:
Flatonia 10:40 - who was still on the field at the time of your posting.
You asked for information from someone who was there, and you got it. I was there.
Now, granted, you may have been looking at the original schedule put out before a couple of bands dropped out and the schedule was revised.
Ratings are normally held back from directors until they are announced AFTER all bands in a classification have completed their performances. Ratings are posted on UILforms after that announcement, so NOTHING would have been posted by 10:45 anyway. Ratings were released to directors immediately after processing because bands were asked to leave the site after performance by the host school, in order to minimize contact between students from different schools.
All results WERE posted soon after the end of the day, and therefore in a timely manner.
Have a nice day
