From FIG MTC Newsletter December 2022.
An additional grip change is considered an “additional or intermediate hand support” and will be deducted 0.1.
Examples include:
– Zou Li Min or Adler 1/1 turn to mixed grip followed by an immediate grip change to undergrip will be deducted 0.1
– Endo, Kip or Backuprise with overgrip followed by two consecutive grip changes to undergrip will be deducted 0.1 for the 2nd grip change
Elements in mixed grip (Giant Forward, Endo, Backuprise, Kip etc.) followed by one grip change to undergrip will not receive a deduction.
Note that WAG are rarely, perhaps never, deducted for similar unnecessary grip changes.
