Annie notes for stewarding, please add to or ask Brian questions about best practices.
Because this was an invitational, we ran the "Events" "straight through, no rotations." Rotations are used to break up figures in one event when there are many competitors in that event. Ask Brian about it because the mechanics were confusing to me.
You refers to yourself as steward, warm up skater is the skater on the warm up circle, competing skater will be skater actively being judged.
First step as a steward is to pick up your clipboard and check in with the referee of that event. Put the skaters in order that they are listed on the sheet, not alphabetical or ascending skate numbers, put them in the order they are on the sheet.
Put the first skater on the warm up circle and start the timer. At 1 minute, add the next skater, and on the third minute add the third skater. After that there is no need for a timer. Sometimes before this process starts you can let the skaters do a general warm up.
You then watch the referee to signal when they are ready for the next competing skater, at which point you pull the next skater and send them to the referee. Then add the next skater to the warm up circle. Repeat until all skaters have competed, as the last 2 are on the warm up circle, restart the list with the next figure they are competing. There are two figures per event and when "running it straight through no rotations," you and the referee start the second figure right after the first usually without a pause. Because of this, make sure skater goes back in line after they compete their first figure so that they don't leave or get out of order for their second figure.
Note: sometimes coaches will pull a skater off the warm up circle to give feedback, don't let that confuse you; consider them one of the three on the warm up circle. Coaches cannot talk to skaters on the competing circles, only referees or sometimes judges.
