Not intending to urinate on the parade but it isn't parallel.
"Parallel" is a parallel Femur (bone) to floor. Your depth was just shy of hamstring parallel.
It might seem like I'm picking nits but there's usually a considerable difference in the poundage that you can shifted between these two depths and if Powerlifting is your intention then it's a good idea to practice squatting below
quad parallel - top surface of the legs lower than the knees.
Also, not to sound like I'm jumping on your back, but the guy behind you is and theres no need for it. You are performing the lift in a power rack and you haven't even got the catching pins set and this is especially important in a 1RM attempt. The equipment is your fail safe. Find your depth below quad parallel (by box or second persons view) and set the catching pins a few inches below this depth.
Regardless, this is a strong lift. Lots of potential!
