Net Promoter Score as a percentage

Given that the NPS is defined as the difference between two percentages, why is it incorrect (second paragraph in the Overview section) to write it as a percentage? I would argue the reverse. JanCeuleers (talk) 10:52, 2 January 2012 (UTC)

I have tried to make contact with the user who contributed the edit that introduced the statement that it is incorrect to express NPS as a percentage. I am going to remove this statement for two reasons:

In my experience, most companies that use the Net Promoter Score express it as a percentage. Not that I am exposed to a huge sample of companies that use NPS, mind you.
Mathematically, a difference between two percentages is itself also a percentage. So even if companies like Satmetrix and Bain usually express the NPS as numbers between -100 and +100 rather than as percentages, that does not make it incorrect to express it as a percentage.
