I thought I would get the varied opinions from folks on this board regarding this seemingly simple maneuver. Since people from all over the FAI universe read this discussion board, we should get a fair sampling of the global interpretation of this maneuver.

I have heard two interpretations of this maneuver: 1) the half outside loop portion of the Reverse Split S begins at the instant the wings have reached the level attitude during the 2/4 point. That is, there is no visible pause after completion of the second 1/4 roll.
2) the 2/4 point roll is not complete until the wings have been level for a duration which would be equal to the first point of the 2/4 point roll.

Which is correct and why? I ask because the rules seem somewhat fuzzy. They state : "From upright, perform 2 points of a 4-pt roll, and push immediately to a half outside loop" and also "In the Immelmann turn and split S manoeuvres and variations, the half roll, snap-roll, point-roll, or full roll should be performed immediately after or before the half loop as required by the particular manoeuvre. A visible line in between the two components must downgrade the manoeuvre by 2 points. Similarly, if the half roll, snap-roll, point-roll, or full roll is performed too early, the manoeuvre should be downgraded, using the 1 point/15 degree rule".

Well, what is the completion of the 2/4 point maneuver? Wings level, or after segment length equal to first point? If interpretation 1) is correct then it seems the maneuver should be described as two 1/4 rolls, not a 2/4 point roll. If 2) is correct then it seems the rules should clarify that.

Now I will sit back and read the ensuing thread. By the way, I see merits in both interpretations but don't really care which way is correct as long as we are consistent.
