Pufff... That's not like it was his idea. ISO 11904-1/2 DF has existed since ever, and JM-1 DF is just translating it to 5128; comparing that DF to the 5128's DF is hilarious.
Anyone with a little knowledge ignores treble and is adjusting length modes annoyance by ear anyway, so one would reach the same result with either DF.
