COMMENTS
The first 65 generations of A306211 were computed explicitly. Since the tail of each generation is the RUNS of the tail of the previous generation, if we start with a complete generation then we can get just the tail of some further generations by iterating RUNS on it. This allowed the computation of the remaining 55 terms.
Generations 11, 16, 25, 42, and 75 end in a 4. The number of generations in between those which end in a 4 is thus 4, 8, 16, 32.
