Distilling the info into one number is tempting, but it's highly political and suspicious as well.

If YOU do it, the uninitiated will suspect you've chosen to give more value to your stong suits, and have "cooked the books", so to speak.

If an organization does it, there is still some suspicion that the organization did the same thing, but for other reasons.

I'd say that to the average person, if an organization did it it would bear more weight than if an individual company did it.

Then we have people who are critical thinkers.

They want numbers and math.

So, my answer is both, and show and explain the math for the idiots like me...LOL
