Assign Slider setting

[sugarplumsss]

When we create a registration, is the position of the assign Slider effective of the volume of that registration?
I use the slider in default keyboard volume mode.

I was wondering, if the position of the slider at the time of saving a registration, might account for otherwise unexplained volume differences.

I have one registration that is slightly louder than another, which appears to be identical.

Anyway, is the slider position, not a consideration when saving?
Thank you and Happy New Year.
