In the F.A.I. rule book for 2008 manoeuvre P-09.01 says, "From upright perform 2 ponts of a 4-pt roll." In section 5B.7.3.D the description reads "Point-rolls within a manoeuvre must have the same roll rate, and the points must be of equal duration on each point." So, if you perform 2 points of a 4-pt roll the knife edge & inverted flight must be of equal duration. P-09.11 Reserve 4-pt. roll (2/4-pt. roll in one direction, 2/4 pt. roll opposite). From inverted, perform 2 points of a 4 pt roll in one direction, followed by 2 points of a 4 pt. roll in opposite direction, to exit inverted. The discription "perform 2 points of a 4 pt. roll" for P-09.01 and P-09.11 are written exactly the same. I have never see anyone do a reverse 4 pt roll and when the planes wings hit horizontal immediately reverse to knife edge. Everyone knows that all the points in a 4 pt - 8 pt are of equal duration. So, if you don't reverse and roll to knife edge immediately then you also don't push to an outside loop immediately in P-09.01, you fly inverted for a same duration as knife edge. This is NOT interpetation this is what the rule book states!
Well stated Mr. Kimbro.
Thanks,
