Hey F1ForHelp! No worries, you should always feel free to bring up a concern if you think there is a mistake or that we could do something better!
Dogen is awesome! I took his course last year, up until about episode 33, which I think may be the devoicing lesson, and I loved it. It changed the way I hear the language. He keeps updating the course with revised lessons and new native audio as well. The quality is definitely high!
