When referring to the World Championships with one word, it's "Worlds," no apostrophe. Similarly, the one-word name for the U.S. National Championships is "Nationals," for the Canadian National Championships, "Canadians," for the Eastern Sectional Championships, "Easterns." The various regional championships are called "Regionals." I have no idea why and my spell-checker hates it, but the upcoming competition is Worlds.
Axel is spelled with a capital A and an x, e, and l, in that order. It's not spelled "axle" like the car part.
Axel Paulsen was a real person and we use the actual spelling of his name. Similarly, the jumps Salchow and Lutz are capitalized, while the jumps toe loop, loop, and flip are not.
"Anti" is a prefix that means "against." "Ante" is a price or cost. "Up the ante" is an expression that comes from poker. When someone ups the ante, it means that the stakes are raised and the risk is increased. When we're talking about a pair team adding a 3ATh or 4STh, obviously the stakes are raised and there's the possibility of an increase payout in the form of base value, but the risk also goes up. Some of the risks are obvious. The obvious risks range from falling on the throw (-3GOE, -1 fall deduction) to falling on a downgraded or underrotated throw (lower base value, -3GOE, -1 fall deduction [it's pretty much impossible to stand up on a cheated throw triple or quad]) to falling on the throw (insert standard deduction here) and having the fall knock the wind out of the girl or disrupt the program or deplete so much energy that the rest of the performance - technical and components - suffers.
Less obvious of a risk is landing the 3ATh/4STh and being so excited that the rest of the program suffers. More than once, I've seen a boy land a 3A for the first time in competition and then pop six times. This isn't something that you can really address in practice, because
in competition is the key.
Perhaps even less obvious: adding a 3ATH/4STh for competition requires practicing it. In and out of the program. On days when it feels "right" and on days when it doesn't. The risk of injury when doing a 3ATh/4STh is astronomical. Seriously, astronomical. There's a reason why we don't see very many of them. Almost no one can practice them day-in, day-out without injury.
Perhaps even less obvious than that: there's very little to gain for a U.S. pair by trying 3ATh/4STh at Worlds.
Barring disaster, the U.S. should qualify two pairs for the Olympics with almost no chance at three spots. After Nationals, there was this moment when the possible entries for World looked like this:
Marissa Castelli/Simon Shnapir
Caydee Denney/John Coughlin: hip surgery, unlikely to compete
Alternate 1 - Alexa Scimeca/Chris Knierim: foot injury
Alternate 2 - Felicia Zhang/Nathan Bartholomay: minimums not met
Alternate 3 - Lindsay Davis/Mark Ladwig: broken up
If you were U.S. Figure Skating looking at that line-up with a goal of "barring disaster," would you encourage Castelli and Shnapir to try a 3ATH/4STh at Worlds? Or would you tell them to wear bubble wrap for the next two months and oh, by the way, the goal is to avoid disaster not to increase technical difficulty?
Solo 2A/3S/3T: many skaters, especially pairs skaters, use a very similar entry pattern for 2A and 3S, but a completely different pattern for 3T. If a program is choreographed for solo 3S and solo 3T, and later one of the triples needs to be swapped for a 2A, it's a lot easier to swap the 3S for a 2A than to swap the 3T for a 2A without rechoreographing the program and if you rechoreograph, are there now too many elements in one corner or is the program now too circular or too straight, and... it's much easier to just leave the pattern of the program the same.
