The same case. Got R: 29 L: 29 S:23 W:26 and need 26 in speaking. Generally there have been some people who had their score changed even from 22 to 28, but there were also people whose score didn't change at all or it was lowered. I guess all depends on the rater and also you have to ask yourself a question. Do you feel that I should have scored more for speaking or just hoping for luck?
I thought my speaking was good enough to score 26 at least, but it turned out that I got only 23, so sent rescore request form day after my test on 9th November. On December 3rd got confirmation of rescore and still waiting.
