I do not believe Dody is a troll. From the time he joined and started posting it was obvious Dody is enthusiastic about diving. I also believe Dody wanted to get a lot of training and certifications done. I think he rushed that part rather then doing different types of diving to build up his experience. Yes he made some errors especially being underweighted which I attribute to the "I want to use less weights than others " rather than using what is necessary. He got caught out on that.
I think Dody's wants to compete on his sac rate as well and it's not a competition.
Has his DM training been of any value? I've been diving 36 years and was told by a good friend who runs a dive shop if I wanted to do a thorough DM course to allow 2 months. No short cuts and I would also do courses for servicing regulators, learn the knots needed for the ropes used, learn some of the boating skills and other things. Assisting instructors with students as well as leading dives. I know the dive sites as have been diving at these sites for over 8 years. Dody did not really have that with his DM course. I've met many people who did the quick DM courses from Thailand and some of them you would not let lead a dive.
So Dody posts in a language he is not native in. Maybe his writing could be better. His intent on becoming a better diver is there to be seen. We all make bloopers and he has to make them so he can learn from them. I believe Dody needs to start doing night dives as that is a different experience he needs. After all how can someone be a DM and not lead a night dive or have no night diving experience. For me DM's should have experiences with fast currents, down currents and up currents, done dives where they do not do just the normal easy dives.
Give him time. He has been diving I think since last November 2020.
Nobody called me a troll with my dive trim post.
