Strong pull.
Be careful at the top not to get impatient and lean back at lock out - your knees unlocked because you went back so far. Just squeeze your glutes and push your hips through. I got called at APF senior nationals on that - got the down call but the side judges could see that it wasn't locked. The strength is there though.
I'll leave out any commentary on trying to hit a PR 2 weeks out from a meet and just suggest an opener around 601 or 606.
Congrats on the PR and good luck at the meet.
