(See above Post of Mrs. P for eligibility for obtaining a spot on the Roster.)
Now the selection of those who meet the eligibility will be up to the Federations.
The USFS will use their results of the Nats.
The Japan Fed will use the GPs, their Nats and past performances.
I don't know how the Russian Fed, the French Fed handle it. In some cases the Canadian and Chinese.
How much does a Fed rely on the results of the Euros? I believe Czech Rep. has only 1 eligible in Senior Men, but two very top contenders to decide from?
France has 3 eligibles but 4 contenders
Russia has 2 eligibles but several contenders.
How important are the results of the Euros?
