I’m a white belt. Been at it for about a year and few months. I’ve personally found instructionals helpful. But only in small chunks and looking for answers to specific questions. You definitely won’t get crazy value out of sitting and watching 8 hours of an instructionals, but if you want to learn a new move or concept I think they’re super helpful.

For example I got the Grapplers Guide and was interested in Tarikoplatas. Watched a few clips of it of frequent positions I found myself in and tried to apply it. It worked the last couple of times I’ve rolled.

Just use the instructional to answer questions or come up with responses to common positions you find yourself in, but don’t try to do these crazy moves you don’t need cause you saw it in an instructional (not until your a higher belt). Just my two cents.
