Unless it has changed recently, it steers towards an average of all the 
servers that haven't been eliminated.  The "best" one is only used to 
set the stratum and the downstream error statistics (root distance, and 
root dispersion).

At one time the averaging was weighted.  I'm not completely sure if even 
that is true, now.
