If you want to create 10 m contour interval, so you have to find a primary data ( Your DEM's data) which has spatial resolution 10 meter or smaller like InSAR. Your can't create an interval contour smaller then it's DEM resolution because when you generate the contour using ArcGIS, the algorithm will try to find the nearest neighborhood between spot height ...

As a rule of thumb you generally do not want to set your contours to be any smaller than your cell sizes. There is no point in doing so because even if there were 3 different values across the 30m cell, it would all be averaged to the same. If you are using a 30m DEM the lowest contours you should use is 30m, as that preserves the accuracy of the data and ...

Now, the answer from the developers of the tool, who kindly allowed me to forward the answer here. I translate and do my best to reproduce what I learnt from Dr. Conrad: The only expected input-dataset is the DEM. The tool runs an interative procedure which works with relative relief-position. The same procedure is used to calculate - the vertical distance ...
