I was able to understand this, but then I found that some sliders make other sliders move farther than necessary. I even found a case where grabbing a slider to move it but putting it back to the original position before releasing the mouse button would change other sliders (surely that means either the original positions were inviable or the changes were unnecessary).

UX wise, it would be far easier to understand if the other sliders responded instantly so that I could see as I drag one slider how much it impacts the others, without having to release the mouse at each step to find this out.
