No problem re: writeup, glad it helped.
The instruction is basically MG showing/teaching his game and I have not seen anything on DLR or deep half guard. Rather, the one thing I recall is them showing a vid on defending deep half and noting that you do not initiate deep half guard but need to know how to defend.
Marcelos guard is 1 leg X guard, X guard and butterfly and that is what the technique vids show for guard.
So given that, I think you have a good point and would say MG is not the best resource for you if you were hoping to use it to develop your current guard style.
Thanks, Marcelo with Braulio would of been a brilliant combination. I would say my style of jiu jitsu is a blend of both guys.
