Double Inverting Stall

The rcdb defines the Double Inverting Stall a single inversion. The difference being how much “un-inversion” occurs at the midpoint.

The following logic attempts to explains this and it applies to other inversions such as the Banana Roll and the Maxx Dive Loop. The magic number rcdb uses to determine when a roll or bank becomes an inversion is 135° which comes from 90° + 45° -- the halfway point between on your side and fully inverted. With multi-inversion elements, there needs to be a point where one element ends and the next begins. The inverse of the prior rule is used for this purpose. This means a second inversion cannot begin until the prior has dropped back down below 45°. The Double Inverting Stall does not achieve this.
