IMO

I’m not sure I understand the IMAC BOD sequence selection process and not sure why they try to keep the selection process limited to only a handful. The Known sequence is a piece of the IMAC world that will be flown and judged several hundred times throughout the year. Time and thought should be put into such an item that is so important to the IMAC flyers.

As for the sequences: I happen to know the guy that wrote the Sportsman seq B. The IMAC proposed and the submitted sequences were changed. The submitted seq had a 2-point roll on the output of fig#2 and had a full roll on the 1st and 3rd leg of the diamond. Why they decided to delete these elements I don’t know, but it sure took a lot out of the seq.

My big problem with some of the proposed sequences is the crossbox without a return crossbox. Example Intermediate Seq B.Fig #6. This humpty takes you out crossbox and exits back on a secondary x-axis that is moved out by the crossbox humpty. Now with no maneuver to bring you back into the primary X-axis line, the pilot has no choice but to fly the remainder of the sequence way out. IMO this is no way to design a sequence. For every crossbox maneuver there should be another to bring the pilot back in and exit on the primary X-axis line. This happens in Intermediate B, Advanced A and B.

As for illegal maneuvers. I know that the knowns are not held in the same criteria as the unknowns. But I think the Intermediate seq B fig#1 and the neg snaps on the 45 degree downlines is pushing the limit for legal maneuvers for Intermediate.

Again IMO
