"I don't feel all that bad after a set of squats (not too failure)."
.....do a true 6 rep max...is hard. I don't care if it is a 1RM or a 20RM...it is hard and you should feel fatigued afterward.
"All I am telling you is that:"
.....yes, you are telling me but not showing me any evidence. I have competed in strength and endurance sports...and know that my body would not perform well on contest day if I did a 3-6RM before my heavy set or event.
"1.) There is plenty of anectodal evidence out there and obviously I"m not the only one who's heard of this."
.....Where? From what I see, people on here like aka-tapout and powerlifterjay are not saying to do this type of thing on contest day either. They say that it is a good training tool...but not a contest tool.
"2.) There are physiological principles backing this up. "
.....Where? Do you mean unracking the weight so you know how it feels? What if you unrack it and it feels like the weight of the world? Talk about losing TONS of confidence. Once again, are you talking about doing a 6RM or a walkout with a super heavy weight on contest day?
"3.) Empirical data has proven it works. "
.....Where? I am not for sure if I see the guys of the WSB club doing a 6rm before they walk up to the platform to do a world record squat. I'd like to think that Chuck V had taken some serious weights in the gym on various exercises before he squatted 1k. I have a very good friend who set the world record in the squat and bench press in 1995 with a squat of 1004 at a bodyweight of 239. He did NOT do a 6RM or a walkout with 1200 before he went up there to squat 1004. Hence...I can make an empirical observation on this theory. This is just an empirical observation from world class athletes. I don't see pljay doing a 6rm on the bench press just before he goes for a new PR at a meet either...but maybe I am wrong...I am not a powerlifter.
"Now if YOU think it doens't work, that is your opinion."
.....Yes...I think and have observed. Give it a try...I encourage you to do so. Encourage GF, Chuck V, Steve Goggins, etc...to try this too.
I don't mean to say this as a flame at all, just trying to express my point. There are tons of theories out there and the rumors that fly from them only create problems. A very good friend of mine is a serious squatter (900+) and does not use this train of thought. He also says that if you can walk out a weight...you can probably squat it with the way that today's support gear is designed.
Just my thoughts...no harm intended...just trying to get some more thoughts on the subject.
