Yes, but to do so can require a decade or more.

You learn something everyday. Thanks.

As Sartesian noted, the peak can come at any point. It cannot be known to
have occurred unless the output in the last period exceed all the existing
[not necessarily known] supply. Even then, you can redefine the peak by
measuring it in terms of output per second rather than output per year.
But a peak will occur nonetheless.
I guess with all the baggage associated with peak, I could have used
