I know what you're thinking. "Does the Cannibal have five inversions or only four?" Well, to tell you the truth, in all this excitement I kind of lost track myself. But being as this is an Over-Banked Curve of unknown degree of incline, you've got to ask yourself one question: "Is it over 135°?" Well, is it, punk?
Silliness aside, rcdb-logic works like this -- when an Over-Banked Curve is greater than 135° it is considered a "Cutback" and an inversion. The 135° figure comes from adding 90° and 45°, or in other words, closer to upside down than to vertical. In the case of Cannibal's curve, the degree of incline isn't known and therefore considered less than 135° until this statistic is confirmed.
