Because you wanted boards hashing ASAP, and got them.
Then why not leave the 8 VRMs on for that point??
why are you dodging that? what was the main gain for everyone on taking off the 4 VRMs?? You could keep shipping with 8 until you tested taking off 4.. .how can you try to keep avoiding this logic?
I'm not dodging anything. They were an excessive margin that is of no use now, why would you not cut back on unnecessary components, when proven unrequited to perform optimal? Makes no sense. Why not add 4 extra wheels to your car because you can?!
