The next level of tuning updates have been release and are on the online update service. We want everyone to update to this level and begin using it as this is the beginning of a new series of updates that will be coming out. In this updates the new software will now ask when using Vtune if you want the software to extend the data all the way to 100%. If you chose Yes it will only extend the data provided you captured enough valid data for it during your DataMaster run. So if you do not capture the areas in DataMaster it will not get extended in Vtune. All of this is explained in the Online help files as well as the tuning guide.
