Thays my point. There are so many variables that it will be difficult to know what works and what doesn't. Im not saying that to mock. I have done the very thing you did. However i ran into the same issue. The tree lived but it was very weak for many years. At the end i had no idea what was a good technique or bad as they were all mashed together. Now i continue doing testing on the tree one insult per season. I heave learned much more of what works vs what doesn't.
I get your point completely.
For this initiative stage of training I wanted to go hard because the material was incredibly boring to me.
I wasn't necessarily trying to learn good vs bad technique. My main focus was seeing how far I can push this in one season. As mentioned in a previous post I have a few big pines that I have been growing for years and I want to know what they can take before I properly work on them. So I don't kill my good material.
I have taken this same approach since the beginning of my bonsai journey. It makes it fun for me. For e.g have 3 trees of the same species. Apply proper training and caution to two. The remaining tree is used for experiments extreme design ideas.
So far I have killed very few tree's
