An exercise in underestimation and stupidity

3RFT
5 x 30kg Hang Power Snatch
Run 200m

6:56

Underestimation? I tried the 30kg, pressed the reps and out thought, "I'm not getting 12 reps with that or 4 rounds, better cut it back".
Stupidity? Aside from whacking my nose and forehead as I practised, which is just a lack of coordination stemming from lack of practise, the really dumb thing was 2 reps into the first round I remembered that power snatches just mean catching above parallel. You don't have to receive the bar at full height. Things got easier then.

Nearly went for a 4th round, decided to stick to the (revised) plan and stop at 3 and sulk about it.
