The current Online Help for Pro for the Surface Function - Contour Function lacks proper parameter definitions.
There is an Adaptive Smoothing parameter. The !help states:

Please be so kind as to include minimum and maximum values for parameters like these.
It is not a great experience for users to ping-pong values into the tool to figure out what the range is.
Did the same team that wrote the hardware spec for Pro get a new project to write the Help?
Words like lower, more, less, etc are not helpful in a numeric parameter definition when the parameter range is not explicitly stated.
