again-reference to IDPA because real world stats regarding incoming vs outgoing are not printed out for easy looking at. and when there is incoming fire you are doing everything right or chances are that you will not be around later to learn from the experience. the 'counting' is not taking away anything from your conscious activities--which should be minimal as your training is what will more so determine your survival. remember--very few rise to the occasion--tne many default to their training.
the counting is but another tool in your toolbox of skills. granted it is not common to find that skill in others, yet i have meet 2 others that have it.
looking for more am i
and as for trying to count rounds while being shot at = your dead shoot them and get away never stand and fight
nothing in this conversation is about 'trying'. i would recommend getting well grounded with the basics before trying anything....else.
