Yeah, these are all over the place. You do different things wrong nearly every rep. I get where you're at - you're frustrated, nothing is locked in, and you're casting about for a form that will feel solid. But this is not the way to get there.
1) 1x5 on deads. Sets across are unnecessary and may well beat you up too much.
2) No belt at 215. It's going to make it harder to get into the proper position and it's another thing to futz with/think about when you really need to focus on the basics of the lift.
3) Do you have a belt on under your shirt? Your lower back looks very round to me, but it might be the belt. If it's not, we have se work to do there.
4) The larger problem is that you're not consistent. I can't really tell you what to fix because you do something different each rep. I'm not trying to be a dick, but to be helpful, here's what I'd suggest: take 30 lbs. off the bar. Re-read the deadlift chapter in the book, and then go in and try to replicate that technique as best you can. But most importantly, do the same thing each time. If it's not right, at least it'll be consistent. Video your work set and post it here, and then we'll work on taking that consistent setup and making it correct as well.
Ya dig?
