The fraction of packets discarded during bursts since the The fraction of packets discarded during bursts since the
beginning of reception, expressed as a fixed point number with the beginning of reception, expressed as a fixed point number with the
binary point at the left edge of the field. This value is binary point immediately after the left-most bit. This value is
calculated by dividing Packets Discarded in Bursts by Total calculated by dividing Packets Discarded in Bursts by Total
Packets expected in Bursts, multiplying the result of the division Packets expected in Bursts, multiplying the result of the division
