Thanks VK, I knew you would come through on this one.
While you sent the French page to me, I know found it on the Swedish page. I failed to scroll down to the bottom of the Executive Club landing page. I contiuned to look in other sections.
Just so I understand this clearly;
Assume I fly ARN-LHR in CE on Nov 1, this gives me the required 400 TPs. Then from Nov 1, I must earn another 800 TP in one year or is it between Nov 1 and my original date of April 30?
