In an earlier part of my life, I've worked on jet engines, diesel and gasoline engines. I've worked on hydraulic, pneumatic and for the last 20 years computers. I've never been instructed by any reputable company to tighten a device using an eyeball or 50% feel tight measurement. If their engineering was done correctly I would expect their documentation to reflect the same degree of professionalism. Now for those who sucessfully tighten their screws 50 percent, I wish you the best. If it's only 50 percent tight, then there's a 50 percent chance of them coming loose. Good Luck! My bet is with a manufacturer to designs things to hold together 100 percent!
Correctly engineered, the damn thing should have shims, spacers or whatever, and then tighten the screws 100 percent. Is that so damn hard?
Apparently it is and thus why this thread partially exists. It's still a FU move from AC to just coming out with a half assed solution, I really hope none of you buy this crap. 50% of tightening a screw... wtf does that even mean?! I completely agree with you Warmonger101 this is all guess work and 50/50 chance to break your card.
