Thing is, no authority requires an all engine go around during training. Yes, of course it is part of the basic typerating. But with the low go around rate nowadays, in my company around one every 3 to 5 years per pilot, and no requirement to train it during simulator events, it is the least trained thing by far. Of course dual engine go arounds are trained every six months, but only during LVP training and that is on autopilot. Apart from that the only thing trained is OEI go arounds.
