What she is holding: Left flag down and to the left, right flag straight down.
Two flags, eight positions, one arm holding still. Start with the first circle.
Circle 1 · one arm parked straight down
The letter A
Seven letters for the price of one idea. Park an arm at your side and walk the other one round the circle from low-left, up over your head, down to low-right. That is A through G, in order.

What a round is worth
- A sign read correctly — 10 points. 12 signs a round, one guess each.
- In the camera modes the number is your hold, not your pose: the spread of your arm angles over 1.2 seconds, in degrees, turned into a mark out of 100.
- Getting the pose right only gets you measured. Everyone can hit R once; holding it dead still is the job.
The flags that matter more
Semaphore is the guards talking to each other. The flags flown on the stand are them talking to you — green, yellow, red, and the purple one that means something is in the water. Those are worth knowing before you swim, and they are on the beach page with what each one actually requires of you.

Before any guard climbs a stand, the surf rake has been over the sand in the dark and gone again. That shift is its own game.
