It does handle border values:

benste@vaiofe31m:~$ nvclock -S -10
Changing Smartdimmer level from 30% to 20%
New Smartdimmer level: 20%
benste@vaiofe31m:~$ nvclock -S -10
Error: The proposed Smartdimmer change would result in a brightness level lower than 15% or higher than 100%.
-> ther is an error and level doesn't go deeper:

I'll try your solution
