Chipper with a Tabata time scheme

In a Tabata Format (20 second Work/10 second Rest) complete the following:

60 Power Snatches 45/30 (6min time cap)
30 second transition
70 pull ups (6min time cap)
30 second transition
80 back squats 45/30 (6min time cap)
30 second transition
90 Wall Balls 20lbs/14lbs (6min time cap)
30 second transition
100 push ups (6min time cap)

Score is reps... For every 10 seconds completed UNDER the time cap add one rep.

ex: if you complete the 60 snatches in 5 min - you get an extra 6 reps (60 extra seconds divided by ten...)
