Its better punctualize what really is SA to avoid certain nonsense I've read here.
When you begin your action, having SA is not only tracking your enemy in 1Vs1
Sa means having consciousness of your alt, your speed and potential, having planned in a second your position to attack, the position of ALL the contacts near you, their speed their E ,directions, potential of threath and the point of your egress or escape after the action (that do not means to run, but find the convenient position to repeat/reprogram your attack.)
Not to mention the consciousness of the landscape under you, tha can be useful in case things are not going right.
Its rediculous thinking of SA as a scanning a bit the sky above and then happily slip in a turn 'n' turn in 1vs1 ad libitum.....
Your SA improves and its heavily proved when the situation around you is total chaos, enemies are over, under around, and they attack you without no rules , no mercy, ready to pick you ( yes pick!!!) at your minimal error, at your first distraction, when you are drooling for a kill target fixating.....
All the rest is speculation on the way to intend flying and fighting....but this is a neverending debate.
