It's so important to analyze every mistake, no matter how minor and learn from it. That's a huge safety factor and one of the best things about video. It allows us to review exactly what happened, often in slow motion. I've watched a lot of your videos and have been mightily impressed at how fast you developed as a climber, faller, rigger. That said, I would invite you to change your attitude. You dismiss your mistakes regularly, losing valuable opportunities to learn and improve.
We all make mistakes. I curse mine and feel so bad about even the little ones, then review them over and over until some way to make sure it doesn't happen again becomes clear.
There was zero reason to tip the limb at 5:24. That monster walnut limb you tip tied in the "near death" video helicoptered around the tree and came 6" away from killing you, 100% DEAD! What did you learn from that? Apparently not!!! If you had but tied the piece at 5:24, it would have swung down and away. There was plenty of room. So why did you tip tie it? That's the question you need to ask yourself if you are going to learn anything here.
It was clearly close enough to scare the other climber. You could hear it in his voice when he called for the goundie to let the piece run. That's a helpless feeling. Then when he was trying to say so in a nice way, rather than apologize and try to learn from it , you just laughed, justified it, and dismissed his concern for safety. While there are no physical consequences to that near miss, there are definitely mental consequences.
It's like a groundie that stands just a little too close to the drop zone. He may in fact be safe, but if the you have to think about it, for even a second before making the cut, it throws your concentration off. Now Brian's fight or flight response has been triggered and he's thinking about you, should he be up there with you?, is he safe? what will you do next?... Perhaps all very subtle thoughts in the back of his mind, but enough to throw off his concentration
