I am not a successful traditional bowhunter, yet - only a novice traditional archer. So, speaking only in terms of traditional archery, and speaking only of my personal experience, being aware of / in tune with my equipment has been very important.
I started traditional archery before I knew of TradGang, or any other website source. I am a reluctant technology user. So, I started as I did years ago, by trial-and-error experimentation. And while I was all over the place in terms of equipment and practices, it did allow me to learn & become very familiar with my equipment. So as I found other resources and, began educating myself, I was able to "reverse engineer" a lot of what I was doing, to determine where some of issues may be off track. In some cases, I was way off - in others, I was much closer than I would have expected. That really helped me, and my learning process.
I read once that Bobby Jones, perhaps the preiminent golfer in American history, did not have a matched set of golf clubs - an apparent hodge-podge of various makes, that would resemble a thrift-store collection. However, at some point after his retirement or perhaps his passing, someone analyzed his chosen set. And they found that each club was nearly identical in terms of shaft stiffness, swing weight, flex point, etc. He did that through "feel" and practice. Amazing.
That is what I would like/aspire to do. But I have the luxury of technology to help me.
