Jack Reape Deadlift Challenge

I had a client skip a session with me on Friday, so I decided to get this in.

This the Jack Reape Deadlift Challenge. The details of the challenge are as simple as can be: Do as many 315lb deadlifts as you can get in 30 minutes

I got 154, and here was the reps scheme that I used:
Top of the minute:
315 x 13 x 5
315 x 6 x 6
315 x 1 x 5 (started to get a headache due to bad breathing patterns)

Top of the :50
315 x 4 x 3 (starting feeling second wind)
315 x 7 x 4

Top of the :45 (so that I finished "while working")
315 x 2 x 4

If you don't like this notation, here it is with the "start time" of each set noted:
