How much can you adjust the suction on this model? Is it just different 5 levels to correspond to the 5 different hose sizes listed on the control panel, or do you get wide range of suction within a given hose size?

We have not received inventory yet for this new tool that ships beginning Aug. 1st. But, according to Festool it has 5 levels of suction. Based on one of the videos that we saw, it appeared to be closer to 10-15 levels.
