Ive been trying a much slow backstroke, for some reason I think its helping. maybe just a moment more to micofocus on the aim?
sometimes I find that distractions ocur, in my mind or in surroundings, so taking a moment more to "feel that moment" is hard to describe.. you know , you get to a place in your head where you say ok I got this shot.. bang and you did..
sometimes a step back and re-aiming helps especially if it's a distraction from another person.. no need to comment or be rude, just recognizing the moment is wrong and trying over rather than letting go resulting in a miss can help, for me.
also maybe a polite way to say shut up you are distracting me.. you want to talk so I'll stand up and give you my attention, ill look you in the eye and listen.. then I'll shoot.
the body language is often enough.. no words needed... My theory is the "offender" is going to just plainly realize that he was (either inadvertently or consciously) , sharking you and that your reaction was to look after that before committing to the stroke.
Chances are he knows exactly why you stopped and stood up.. a battle of words is of no help unless you want to be a cop.. being in control of your shot is your right to assert.. If he was just making a wisecrack or a joke then why resort to a big discussion, stop and laugh at the joke, then shoot. If you shoot while laughing you surely miss..
I do that at work as I work with tools, people come up and talk, drill me with questions on this or that. I stand up put the wrenches down, give them the attention they need, that way I'm not screwing up as often by being distracted.
Doesn't take long for them to realize you aren't playing into it and they are preventing you from working.. then I'll end the conversation and go back to my own focus, rather than trying to divide it.. Same basic theory applied..
I find This a nicer way to deal with the issue than verbalizing that they are distracting you..to which there is some chance of backlash , denial etc.
pros might have less distractions than many other real world atmospheres.
A judge may intervene in the sharking if its a pro.
We mere mortals don't usually have that as an option. tuning stuff out is a skill in itself. Sometimes its a worry that popped into your head, or similar.. If you dont take things to the point of ridiculousness, I think that helps,,, for me anyway.
