I'm of the feeling that they will send Kailani to the Olympics and Brooklee to Worlds.
Australia, in recent Olympic cycles (2005-6 season, 2013-4 season) we seem to always have the problem of having 2 women's skaters of a similar level fighting for one spot. I just hope this cycle, there won't be any calls to the arbitration of sport.
They will probably select either another Senior B or Challenger AND THEN Four Continents.
I suppose this is Australia's way of holding qualification rounds like South Korea, but using international competitions instead of having to create their own test skates. I suppose by doing this, they attempt to make a more 'objective' selection instead of doing the 'body of work' profile thing that we saw in the US last olympics.
It's confusing as ever, but I generally understand the premise.
Assuming the stupidity of this document is to take out the junior scores and the two skaters need to go head to head. In your scenario why on earth would they go right up to 4CC as the last event? It is too close (13 days) to Olympics gives zero time to the athlete eventually selected to prepare. Will the selected events benefit the skaters from gaining further world standing points, finding comps where we can enter 2 skaters, who is funding the trips, what happens if one or both get a Grand Prix event in the mix. By the time Olympics come around either potentially could be burnt out. Already Brooklee has done 3 Internationals no podium finishes. Kailani 4 Internationals 3 podiums with all scores except one higher than Brooklee.
There is no consolation prize in the championship policy for 2018 worlds. Whoever meets this criteria (unless it is changed) will go.... If more than one (1) athlete in each discipline has met the above requirements, athletes will be ranked and selected based on the athletes total TES achieved at two (2) Senior ISU Championships or ISU International Events during the current International Skating season.
