I formatted my sd, and I realized that I’m capturing more aircraft with more distance, does this really happen?
Not in it’s self.
Formatting the SD will (obviously) clear all setting and take you back to default. If anything had been changed for the worse, then this will have been cleared.
there is normally no direct impact if you simply reformat and set up new.
but it could be that the settings are different and therefore you can see this.
In addition it can also be that there are simply more planes currently in your area
