It is frustrating the living daylights out of me that it never seems to stick.  Exactly how will I notice the change if I set my Vue unit to equal 0.1 instead of 1, for example?  I have fiddled with various scales, and it never seems to make any difference.  If you can give me an example of an instance where you obviously notice the difference I'd really appreciate it. 

As I indicated in my other post (where you so nicely answered), I thought it was finally time to learn the Function Editor in serious, and with this hickup, I am stumbling.
