If you ask a 4th kyu if they understand connection and how to connect, most likely they'll say they have no clue.
As a 4th kyu-er, I don't really have a clue, as expected, but I am starting to notice and think about things that I haven't before. I'm pretty sure this is affecting my practice. The amount learned may be negligible in comparison to someone who's been around long enough to progress more, but there are still tiny little gems of insight gained at every turn, it's still a journey that's miles from where I started. Recognising them in newer beginners seems easier than recognising them in myself. Imo.
