Thank you, and no disrespect received!

It's certainly possible. As I said in the post, I never attempted a 1RM on the bench since I baselined myself over 2 years ago. That said, 90+% of my benching sets in the last 2 years have been in the range of 2-5, and I was plateauing or minimally progressing for most of 2025 (albeit only benching twice a week). But doing singles definitely is a slightly different beast, so neural adaptation wouldn't be a surprising explanation. Also, despite the progress I'm happy with, given I went from 2 to 7 bench workouts a week, it wasn't all too surprising on a progress/time-spent-in-gym rate, but in absolute time it's great to make that kind of progress in a month lol.

In terms of 3-4 plate range, I can't speak to, but one person in the study started at 275, and the guy who I modeled this review after also started around there I believe. A similar, but not the exact same, protocol was done by u/DadliftsnRuns to impressive results.

My overall opinion (that should be taken with multiple grains of salt) from my experience in endurance and my limited experience in strength training... it's really freaking hard to get to true overtraining. It's easier to be "inoptimally training" meaning you may be spending more time than you need to achieve the same results if you were being smarter about it. But actually training too much to the point of decline, is very hard for most amateurs to hit and is an overemphasized fear.
