[AVT] Reg: Testing RTCP Intervals



I was looking for a document to test my rtp implementation for RFC 3550 and ran into RFC 3158 which states the following;
 
 
Text extracted from RFC 3158 - “RTP Testing Strategies”
 
      o  the minimum interval is never less than 2 seconds or more than
         2.5 seconds;
        
      o  the maximum interval is never more than 7 seconds or less than
         5.5 seconds;
 
      o  the average interval is between 4.5 and 5.5 seconds;
 
      o  the number of intervals between x and x+500ms is less than the
         number of intervals between x+500ms and x+1s, for any x.
 
 
 
Since the minimum interval is 2.5 (initially) with +/- 50% randomization, we will have time interval in the range
[1.25 sec, 3.75 sec] for the participant. 
Why do we have to bring up the minimum time interval from 1.25 sec to 2 sec ?
 
Also the maximum interval is governed primarily by the total number of participants. 
Why do we have to have the upper bound of 7 sec and lower bound of 5.5 sec ?
 
 
Note: If the text is specifically for RFC 1889, then just disregard this mail. If not, let me know your views.
