I went to Brian Howard's regular judging school in 2004 at Desert Aircraft. I went to the Advanced Judging School in 2005 held in Chandler. I was also at the judging refresher at the Tucson Shootout. Here is what I was taught and what I recall.
1. The standard is perfection. Deductions are taken from there.
2. There is no "allowed" displacement on snaps that isn't deducted. As a judge, you have to find a consistent way to downgrade for ANY displacement after the snap.
I think you missed something Dean.
Brian feels that there should be no displacement, however he recognized at both the Chandler class and at the Shootout that the IMAC rules DO NOT define a downgrade. As long as the track of the plane prior to and after the snaps roll is parallel then it is OK. A snap is a stalled maneuver and we cannot downgrade for a displacement that may occur during the stalled portion and autorotation.
