That looks like a much better position for you. Looked like a speed lift this time
.
Since you are really working on nailing down your positioning I would avoid dong 10 reps. 180 isn't exactly light for you although I'm sure it felt fine. It's just that you basically would be better off doing 2 sets of less reps so that you can focus on quality without too much fatigue creeping in and mucking things up. When you are "learning" a movment you really have to think about the larger percentage of your practice being as good as it can be. Your brain dials in movements and if too much practice is done under the duress of fatigue of some kind, local muscular fatigue or otherwise, then it can be counterproductive.
One reason for back offs is not to just get volume in, but to end the session with some perfect reps after you've pulled some very heavy stuff. As you sleep and the brain is sorting through these movements it will "remember" the 8 to 10 good reps more the one or two OK ones or bad ones. Make sense?
It's like if you are practising free throws. 20 good ones from the free-throw line are going to make much more of a difference than 5 tries from half-court.
