in between OEPM pivots things happen, variations happens, dips happen.
The OEPM in it's simplistic form does not take those into account.
It's like looking at a bus route. Yes, will get from point A to point E and final point/stop N, but in between the bus goes sometimes in a seemingly random, even inverse manner.
Accounting for those variations and capturing as much as possible from them is essential.
Also, once we understand at least some of the variations, then any negative variation of the "established" variations will make us understand that the final pivot N is denied.

I lost my files. Don't know how or where, changed few computers. But these theses are from my foggy recollection.

So for example each pivot has it's own importance, like departments into an organization. So when it is reached, the way price reacts is either inside norms or negative - this will forecast next expectations. It's like a chart inside a chart or overlaid.
Also the percentage is BS for OEPM concept. Reason is that it will be way too simplistic. Hence a combination between percentage and abstract numbers is better. Just like warranty on a car, 5 years or 100k whichever comes first..
