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.
I think that you find in actual use that this figure will allow you to adjust for wind drift. I am not certain about the piltos in your area, but out here it is the rare pilot that can keep his seuence EXACTLY on plane for the entire sequence. Plus, the top of a humpty can be very tight which will limit the y-axis displacement. Or if you need it you can fly a very large radius at the top.
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
The BoD determined that the negative snap on the 45 downline would be used in Intermediate this year.
I don't understand why you would design a sequence to compensate for pilot error. A pilot that flies a good wind-corrected sequence will be penialized. A sequence should be drawn to provide good flow period. Let the pilot make the choice on where to try to hide mistakes.
So the BOD decided to allow neg snaps on 45 downlines for Intermediate but throwout a proposed Intermediate sequence because it had a 90 inside roller that had to be flown coming back in from a crossbox manuver.
