Questionable and hard to prove? Negligible Just compare any manufacturers BB30 crankset with their other systems. Red for example, complete system, crank and BB. BB30 comes to 610g, while GXP weighs 714g. 104 grams are saved. I don't know where you come from, but if 15% is negligible, I wouldn't want to be paying your taxes.
Regardless, BB30 really wasn't designed for recreational cyclists(myself included). The added stiffness, and a substantial weight savings makes it great for pro's, who's bottom bracket bearings are replaced after each race anyway.
A little Loctite 609 and most of everyone's complaints are solved.
