have you noticed that there is one point per quarter? that means that the sales of Q4 were record high and loss is seen first on Q1, which is 5 weeks pre WP and 7 weeks post. The slope is less steep because of the sales of the first 5 weeks. After feb11 sales crashed, and the real fall is seen in Q2. So the graph you quote for me enhances the opinion that elop killed the sales
