One of the first things I noticed when I conducted my Deterministic Bass experiment using three time periods of data was a boundary condition:

This condition becomes more obvious when we scan out:

And even more obvious when we scan further out:

But what does it mean? Where does it come from? Is it a theoretical or a practical limitation? What mathematical form might it take, and why?
I soon determined the mathematical form:

The “theory” is in fact a mathematical formula with no theoretical justification other than it seemed to fit the data. But the mathematical fit was less than perfect, and the theoretical justification remained nonexistent, or emergent, to give it a finer sounding moniker.
For the last decade, this situation has remained basically unchanged. There is an observed limit, with nothing else known about it.
Until now.
