Definitely astute question!
I wasn't with my regular coach that day, and while that fellow is great, we don't have day to day training experience with each other. After the second rep he said it needed to go down 1/2 a notch to get it lower on my back.
I feel pretty good about the lifts though, considering I had sketchy unracks which is not common with my squatting. Much more common with my benching.
I dunno about you guys, but I've always said when it comes to heavy squatting, the battle is won or lost at the unrack. So with less than optimal unracks it could have gone worse.
In a somewhat related topic, we were talking about 'the perfect rep'. I'm sure you've all experienced this: a heavy rep maybe a PR and it feels almost effortless. It's happened to me multiple times squatting. . . that feeling: Holy Crap I got this and hit the hole and you feel indestructible. Happened a few times pulling as well, my 500+ pulls in competition felt like that.
I love this stuff. When you have an off day you just want another crack at it to get that golden rep. Maybe it's like the perfect shot playing golf (I don't play golf).
Anyway, apologies for the rambling.
Thanks all for the input.
