Here is a slightly different approach to finding quasi-regularity in Eric's sequence. I calculated a large number of terms of the sequence, the positions therein of the number 18 and the first differences of these position numbers. Here is a graph:


Those varying-length stretches where the graph drops down to the axis are consecutive ones, representing consecutive eighteens in the original sequence.
