This initial position can then be adjusted resulting in an estimated position by taking into account the current ( known as set and drift in marine navigation ).

So, somewhere in our minds we are taking sample points, calculating distance, estimating position and velocity vectors, and changing our location and hand position to catch the ball.

Estimated position data from the Cassini spacecraft was included in the fit, improving the orbit of Saturn, but rigorous analysis of the data was deferred to a later date.
