They haven't posted the announcement yet for the event this year, so I had to go onto Internet Archive to find the 2023 announcement.I looked for, and failed to find, how the countries are chosen for WTT.
From this, it looks like you know! Could you post a link or instructions on how to find this?
On the second page, under Basic Event Format and Qualifying System:
"b) Six (6) ISU Members will qualify based on the scoring scale used for the ISU World Standing points (see applicable scale in sub-paragraph e) below) scored by its best 2 Women Single Skaters, best 2 Men Single Skaters, the best Pair and the best Ice Dance Couple primarily at ISU Grand Prix of Figure Skating events and Final season 2022/23 and the ISU World Figure Skating Championships 2023, plus possibly the ISU European
Figure Skating Championships / ISU Four Continents Figure Skating Championships 2023, the ISU World Junior Figure Skating Championships 2023 and ISU Junior Grand Prix of Figure Skating season 2022/23"
and
"d) For the purpose of the ISU World Team Trophy Qualifying System, the basis is to attribute to each ISU Member points according to the scale below (sub-paragraph e) on the basis of the two best results (the highest number of points earned) of two different Single Skaters Men, of two different Single Skaters Women, of one Pair and of one Ice Dance couple at each of the two (2) groups of ISU Events listed below (the applicable Events):
i) in one of the ISU Grand Prix of Figure Skating individual events or Final (senior) season 2022/23. If Skaters/Couples of an ISU Member have not obtained points in the above-mentioned ISU Grand Prix of Figure Skating individual events and Final (senior) season 2022/23, then the best result in one event of the ISU Junior Grand Prix of Figure Skating individual events (only in individual events but not the Final) season 2022/23 can be considered.
ii) in the ISU World Figure Skating Championships 2023. If Skaters/Couples of an ISU Member have not obtained World Standing points in the ISU World Figure Skating Championships 2023, then it is possible to use the ISU European Figure Skating Championships 2023 respectively the ISU Four Continents Figure Skating Championships 2023 and if needed the ISU World Junior Figure Skating Championships 2023.
It must be understood that in spite of the fact that the Qualified ISU Members for the ISU World Team Trophy can only participate with two Single Skaters each Women and Men, one Pair and one Ice Dance couple, for the ISU World Team Trophy qualifying system the highest number of World Standing points*) per discipline (Women, Men, Pair Skating/Ice Dance) earned at each of the two above-mentioned applicable Events will be used when cumulating the World Standing points*) earned per ISU Member. This means that more and different Skaters/Couples per ISU Member may contribute to the cumulative number of World Standing points*) per ISU Member. Practically, two to four different Single Skaters Women and two to four different Single Skaters Men (the maximum four different Skaters would be two different Skaters each at two Events) could contribute to the cumulative number of World Standing points*) per ISU Member. For Pair Skating and Ice Dance couples it could be one to two Pairs respectively one to two Ice Dance couples per ISU Member that could contribute to the cumulative number of World Standing points*) per ISU Member (the maximum two different couples would be one couple each at the two applicable Events)."
was interviewed recently in Calgary, right after winning Canadian Junior Nationals.
. But, first she has to focus on just the 3A and they won’t add this to her jumping elements, until it is more consistent in practice. She is comparing herself only to what Koreans and Japanese are doing, at this moment and because only the 3A seems to be kept at Seniors, that is the priority. If they see an athlete like Mao Shimada or even Adeliya (1st Senior season) maintain a quad, like the 4T, for 4 or more seasons, then, she will try to learn a 4S more seriously.
