We prove a recent conjecture by Marczinzik involving certain statistics
on Dyck paths that originate in the representation theory of Nakayama
algebras of a linearly oriented quiver. We do so by analyzing the
effect of the Billey-Jockusch-Stanley bijection between Dyck paths
and 321-avoiding permutations on these statistics, which was suggested
by the result of a query issued to the online database FindStat.
