A shot is only as good as the underlying data - AOB, speed, and range. However, some approaches are better than others. Assuming you reasonably accurately determine AOB and speed, you can all but eliminate range by turning so that the gyro angle of the shot is near zero, in practice maybe within 20 degrees of your bow. This is what you should strive to achieve. Then all you need is an eyeballed, rough range at best.
Also strive to get below 1000 m. This mitigates the effect of AOB and speed errors. For example, at 1000 m and a 90 degree approach, you’re allowed up to a knot of speed error and 10 degrees of AOB error.
So in summary:
Approach the target roughly perpendicularly to under 1000 m (but not below 300!) and set yourself up so that the gyro angle is near zero at the shot. This will eliminate range as a source of error, and minimize the impact of possible errors in other data.
Here is one of my videos demonstrating these concepts:
