sorry guys, I found the information on bern 2011 web.
For the pairs there is no preliminary so all go through to short program. I do feel though (as this had be said before in the threads about inexperienced Pairs) this should go down to 12 for the free skate (instead of 16) there will be a huge gap in terms of points between the top 8 and the bottom 8.
In singles, 10 from each discipline will go through to short program, so out of the 20 odd skaters there is a good chance of qualifying for short. If i was them I would scale down my program and to perform jumps that you do consistently and get good GOE on them.
