Shannah,

The FAI 2008 Sporting Code is very clear as to when the loop segment begins relative to the 2/4 roll and roll for Manuver P-09.01...

The following was copied from the 2008 Sporting Code.

P-09.01 Reverse Split S and Split S Combo, 2/4-pt roll first, full roll second, inverted exit: From
upright, perform 2 points of a 4-pt roll, and push immediately to a half outside loop. Perform a full
roll, followed immediately by a half outside loop, to exit inverted.
Judging notes:


The outside half loops must follow immediately after the 2/4-pt roll and roll.


The length of the upper horizontal line (including roll) is equal to the diameter of the half loops.
The geometric shape is that of a Double Immelmann.
