If it was the old chainring that was the source of the problem, then this test
doesn't prove anything. To validate your findings, you should replace the
chainring with a new but not a narrow-wide style, and make sure that you can
reproduce the problem. Then you can conclude that switching to a narrow-wide
solution solves the chain drop problem.
