Methinks you don't understand what intangible means. The relevant definition of intangible is "not tangible." The relevant definition of tangible is "capable of being appraised at an actual or approximate value." So, by definition, these intangibles of which you're incredibly fond cannot be accounted for in metrics, advanced or otherwise.
Another great definition of tangible is "capable of being precisely identified or realized by the mind." So, the best part of intangibles is that, by definition, they cannot by accounted for, even by your feeble mind.
