I have to relate this to striking. My background consists of striking, mainly TKD. I know when I was a lower ranking belt, I could sometimes make a nice head kick on a black belt that would have been critical in a full contact scenero, but big deal: That same black belt would have already made a million critical-like head kicks on me loooong before that.
So while it is a sweet feeling to bask in the rays of self-success after pulling a move like that, you also have to keep it real with yourself, and like other people here have mentioned, remember that higher ranking belts are typically going easy on us lower belts.
Stew (Landry) will roll me and pass on a million submissions, just putting them on me slightly so I know what to feel for, and how to defend against it, before moving onto some other move he feels like working on. He will position himself so I can put a d'arce on him or something, and he will not tap unless he has to. )Which is never, because my d'arce sucks shit right now, but it's getting better.)
When I first started noticing that he was passing on subs, and giving my grips, I asked why, and he said to help me learn what to watch out for, what to grab for, what to feel for, etc.
