What I can say is that I've tried a lot of things over the past couple of years after setting some PR's in 2018. None of my experiments haven't resulted in a better deadlift.

His view was that when he got something wrong, he just eliminated what didn't works and got closer to finding out what would work.
My Advance Complex Training Experiment
My training revolves around Complex Training (Post Activation Potentiation Training) because it works.
Years ago, I ramped it up with what I termed Advance Deadlift Complex Training for a year. In doing so, I ended up taking 50 lbs off my Deadlift.
I then revise the program after that year and increased my Deadlift 20 lb above my personal best.
It was like...
Baking A Cake
I had all the right ingredients but didn't use amounts.
I learned a lot, and I haven't written off all of these experiments because I don't think I stayed with some of them for long enough to reap the benefits they could offer me.
A Common Issue
Everyone has done that. I did that in my early days of lifting.
The biggest issue with many is that in the learning process, they lose ground and abandon the program.
As with anything, time is part of the learning process.
Another issue is that sometimes, the program isn't correctly written or executed. My initial Advance Deadlift Complex Training Program was a nightmare. The concept of the program made sense. However, I stuck with in, realizing that I probably had not written it correctly; which was true.
Some of them took me away from what feels like my best way to deadlift, and those are the ones I really have to think about as to whether or not I want to train them again.
Great Point
There definitely something to following your "Gut feeling".
Why Doesn't It Work For Me?
What I consider is, if it working for other, "Why not me?"
My answer is usually, that the issue isn't the program but me. I either missed a step or two or inputted it incorrectly.
It's like the Baking A Cake story, which is a true story.
I had the recipe. It stated to add a cup of oil. For some reason, I grabbed a measuring cup that was 16 oz, which was two cups.
In my head the cup was "a" meaning one cup, which it wasn't, So, I added two cups of oil.
My wife figured it out after I went over it with her. Evidently, I wasn't smart enough.

Baseball
"It better to fall on your face going for the ball than fall back on your butt waiting for the ball to come to you." Billy Martin
The same is true with trying new thing with lifting and life in general.
Also, you will make over a million dollar a year in baseball if your batting average is over .300.
That mean your right 30% of the time and wrong 70% of the time
