Crossfit Total

Ok so today was the CrossFit Total, 1 max rep for Back Squat, Overhead Press, Deadlift, add those numbers together for the total. The last time I did this WOD I hit a personal best in the deadlift (435#). Since then I've hit 435# a couple of times again but I'm kind of stuck there. A few weeks ago I tried 455# and that didn't get off the floor, so today I tried 445# and almost had it but almost doesn't count. I've got to count the 405# as my last hit lift. On the bright side I tied my PR in the Overhead Press 175# and I'm on my way to, albeit slowly, a 400# squat, today I did 335# my PR in the squat is 365#. So my total was 915#.
