I can say when I try to modyfy default nodes to do something specific I don't understand a thing . Moreover I don't understand a thing in my oun pixel processors a month after untill I write huge documents describing evrything that takes me forever.
The reason IMO is because SD provides zero clue what goes from one node to another .
Please do it Blender way where we have special viewer node and spreadsheet showing what is going on.
I am so tired to copy/paste nodes in value processor just because it at least shows you some numbers .
Ideally it should both spreadsheet with numbers , and pixel preview with "normalized: button as in some 2d compositors.
Some fileld vs single value only indication maybe like in Blender.
