Assuming they didn't change their jumps to take advantage of the new rules, that puts Plushenko a little over 1.15 points above Lysacek. So what if they knew about the new rules and changed their programs accordingly? Could Lysacek have added 1.16 points between the SP and FS?
....
Rule what if's, assuming all the proposer content rules pass (and they probably will).
If you eleminate the second step sequence from the short programs and score the second step sequence in the FS as the soon to be ChSt element, Plushenko again wins. In addition, if he has a 4S Pluchenko adds a second quad to the SP and opens up his lead by several more points. Both skaters will have to adjust their spin features to adjust for the new features requirements, but that probaly willnot chage their leves or scores much.
If Lysacek does not have a quad in the short and the long, and Plushenko has two each in the short and the long, I don't see how Lysacak overcomes the changes which all faver the quad (call them collectively the Plushenko rules).
A underrotated 4T with 70% scored at -2 will get 5.2 points, where 3Lo is 5.1 and 3F is 5.3 in BV. So he is better to do the triples well and get +GoE which will give more than 5.2
A fall on 4T now will give him 6.3, which is more than the 6.0 BV for the 3Lz, so maybe it is worth trying the quad if he can get all the way around on it. But even so, if Plushenko has four clean quads and Lysacek tryes a few and falls down, I expect Lysacek still loses.
The rules seem clearly designed to make it much more difficult for a skater without a quad to win. It is ironic that after the Men's event, the ISU bigwigs (including speedy) rushed to say the result was exactly right because the system was designed for the best all around skater to win. And then they go home and cook up new rules that favor a Plushenko type skater over a Lysacek type skater.
(added after running the numbers)
Remove the second steps sequence from the short, make the second step sequence in the long ChSt, give Lysacek a 4T in the short and the long with a fall on both, Lysacek wins. Then give Plushenk a second quad in the short or the long, Plushenko wins.
