The sign in Row 2 matches the sign in row 3 perfectly in each week. How many more weeks will the predictor "work?" Or, will we stray from the model and follow the 2012 pattern? We are currently in week 11.
Obviously weekly 11 is not finished yet. The percentage change will resolve by EOD Friday. To Ahimsak's point, I agree. 2013 feels like 2012. The last row above shows what happened in 2012 starting next week. We topped April 1 then dropped through June 1.
