Comment (by A. Sinan Unur <sinan@…>):

 Leaving aside the fact that the point of the P^2^ algorithm is to deal
 with much larger sample sizes, there is no reason the implementation
 cannot return the exact median for ''n'' <= 5.

 It is the P^2^ algorithm's ''approximation'' that kicks in when the 6^th^
 observation arrives. Your implementation could simply return the exact
 median until then.
