Indeed indeed. I put 210/10 as my answer but according to the answer sheet the correct answer should have been 210/20.
I challenged this as everything I have studied suggests backing of 30deg and reduction od wind strength of up to 50%. The closer answer would then be 210/10 but the answer sheet disagrees.
After discussing this with the Chief Flying Instructor he eventually agreed that my answer was correct and the official answer was wrong. Oh well, I'll give myself 95% this time then..... lol.
