NADEAU: 30 SB List, 56 WR List
SADOVSKY: 25 SB List, 62 WR List
ORZEL: 44 SB List, 47 WR List
At this time, none of the Nadeau, Sadovsky or Orzel are top 24 on either Seasons Best or World Ranking.
Sadovsky and Nadeau are close to top 24 on the SB list, but they could move down if men below them get higher SBs at Worlds. Orzel could move up on the SB list if he gets a higher score at JW, but probably not high enough (Gogolev's SB from the JGPF is at #26).
The WR gets purged after Worlds, eliminating the oldest year of data, and cutting last year's data down to 70% of its value. Several top-ranked men will drop drastically due to retirement (Rippon, Ge, Yan, Hendrickx, etc) or diminished recent performance data (Besseghier, Kovtun, Petrov). Orzel has the best opportunity to move up, since he will be going to JW so good results there plus list reorganization could move him at least near the top 24. Nadeau and Sadovsky have no more assignments this year and are too far down to make that big a leap based on list reorganization.
But the top 24s give guarantees for initial host selection. Host pick is another way to get on the GP, as well as alternate selection (based on SB). All three could still make the GP by one of the alternatives.
