I am sorry to cause confusion here Stephan. I mean something very simple that does not require going back to your previous posts.
Every week your make a prediction for next week's annual increase. And every week you refer to your previous prediction and say whether you were high or low. But you don't post explicitly what the resulting annual increase was. Anyone can calculate the annual increase from your numbers by subtracting your second number from your first number, but I think it would be helpful for readers to post that number explicitly.
