Too much back rounding on the dead?

[confuzzl3don3]

So after my bad bout of deadlifting which slowly saw me go from 158kg for 3 reps, to 2 reps the next week, and the third week i couldn't even get 150kg off the ground. After re-reading SS i realised that my stance had become too wide and my grip was too wide making the lift more difficult for myself. Fixed that this time and got 158kg for 5. The problem is i felt the back was too rounded (i think this is related to how my chest seemed to not be kept up enough). What do you guys think?

For a comparison check out my 155.5kg deadlift about a month back

Your form not bad at all, cant be too perfect. There is a little rounding but i think is acceptable.
I check both of your video, they both look the same to me.
Again fuking strong!!!

I don't think it's too bad. I'd probably be more careful on the eccentric. It's common to relax a bit too much and lower it too slowly. That can lead to injuries. I'd just set it down much faster, a controlled drop.
