I have done some research about the trend in the Fusilev sales and the Wolter Kluwers data.
The trends is chartet below. The Fusilev sales is the Actual sales every quarter. The Wolter Kluwers sales is a 3 monts single moving average multiplied with 3 (to get a whole quarter sales). It seems like the WK sales are an eksponential trend while the actual sales numbers are a linear trend. Do your own DD.
