10a0 represents the percentage of time your Aimpoint was within the “absolute 10-ring" (imaginary 10-ring drawn around your AAP) in the last second before the shot (control time intervals can be adjusted in your settings).
This parameter should be explored when a shooter doubts his/her calibration, suspects that the sights are slightly off or a shooter suffers from astigmatism, yet the hold stability remains solid. Generally speaking, 10a0 could be utilized by virtually any shooter depending on what subtlety needs to be addressed during the practice session (one could very well practice his/her hold stability with alternative areas on the target rather than the bulls’ eye, for instance). This parameter comes in handy for shooters with decent hold stability but lackluster sighting/aiming when they need to objectively evaluate their hold stability ”in a vacuum”.
This parameter shall be treated differently compared to the 10.0 one that was covered in our previous post. Even though this is a relative variable, a shooter should focus on keeping the 10a0 percentage as high as possible. Thus, the closer you are to 100%, the better!
Feel free to share your personal tips in regards to the 10a0 parameter in the comment section below
