It affects the first few segments until bpsAvg gets bigger than 0 due to the fact that the observers of HTTPConnectionManager do not get notified until bpsAvg is bigger than 0. This is a problem because then you would select segments, and not only the initsegment, with a high bandwidth that is not available.
