The purpose of vdroop?

[Geek77]

Should be plenty of explanation right here: http://www.thetechrepository.com/showthread.php?t=126

If you haven't already read it

Holy smokes.

I think I got even more confused then I was before.

Is there an explanation in English? ( unfortunately I dont speak Rocketscientish )

I know there are people here who do, so could you (please kindly) translate?

VDroop is inevitable, right? Is there any way to control it without VMods?

How come the manufacturers dont make MBoards that would have less VDroop if it's possible with VMods? I don't mean tweaking the heck out of it - just control VDroop better? They have all the means for this to be done safely... Improved performance would sell more motherboards and bring more recognition by experient users. Am I wrong?
