Double-twisting double tuck
Oh, the controversy this caused. When Simone Biles originally performed the double double off beam at US Nationals in 2019, it was given a provisional rating of I.
This seemed logical. The full-twisting double tuck is already a G, and on other events, the progression of elements from full-twisting double tuck to double-twisting double tuck is rewarded with a two-tenth (or three tenth) increase. On bars, the full-twist dismount is a D, while the double twist is an F. On floor, the full-twist is an E, while the double twist is a H. So, the only option would seem to be to reward the double double on beam by valuing it at minimum two tenths higher than the full-twist (an I), or even three tenths (a J).
And then the women’s technical committee gave it an H, just one tenth more than the full-twisting double tuck. Biles responded by performing it exactly once to get it named after herself in qualification, and then not again.
This affair exposed much of the hypocrisy and inconsistency inherent in the entire code of points and the valuation of elements, which makes no sense, almost ever.
