I’ve not said the code should encourage twisting on the table? Exactly the opposite, Tsuk should be seen as 1/2 directly onto the table and deducted for doing noticeably less (a little leeway is okay, a good 1/2-on entry may still have a tiny bit of twist happening onto the table and not be a perfect 1/2 rotation on).
As it stands, twisting on the table is already allowed without penalty for Tsuk. It’s seen as a backward vault with “1/4 to 1/2” in first flight. If less than 1/2 is happening in first flight, there’s going to be some twist happening on the table to get into backwards position.
Every Tsuk double salto vault ever competed twists significantly on the table. That technique honestly may be necessary to do a Tsuk double salto. It’s the kind of thing where we should coach it that way, but it’s correct for the code to deduct it still, because Tsuk vault receiving a higher start value already negates the deduction.
