Usually the tech specialist follows one skater and assistant the other one, tech controller has the superior control over it, then during review I suppose they vote about the reviewed elements.
In "live", Technical Specialist 1 (here Towler Green) calls the Women and Technical Specialist 2 (here Pedrazzini) calls the Men. Technical Specialist 1 calls Lifts, Spins and Choreo Elements.
For the Pattern Step Sequence, the procedure is:
TS1 names the difficult turns performed by the Woman and will say “yes or no” based on the execution. TS2 names the difficult turns performed by the Man and will say “yes or no” based on the execution. When two (2) turns are performed at the same time, TS1 will name the difficult turn performed by the Woman and will say “yes or no” and then TS2 will name the difficult turn performed by the Man and say “yes or no.” Simultaneous execution of two (2) difficult turns can only occur once in the PSt. TS1 calls the level for the PST at the end of the elemen
If any member of the Technical Panel sees a reason to review an element, they say
“REVIEW”
The TS2 and TC must keep track of the Reviews and Falls.
TS1 must also write down ALL steps during any Step Sequences/OFT/PSt performed by the Woman.
TS2 must also write down ALL steps during any Step Sequences/OFT/PSt performed by the Man.
Both TS2 and the TC write down what was called (Required Element and Level) during the program.
Before the Elements are authorized, the TC will verify with the panel the Elements and Levels are correct. If both the TS1 and TS2 state “agree”, the TC states “Elements Authorized”.
