> we run HDLC on DS3 and we max at about 40.something too

if you're using five min (or three min) samples, and you're seeing 70%,
peaks are likely much higher and some users' packets are being dropped.
by 80%, enough packets are being dropped that users are likely to see
the effects of exponential backoff.  things do not improve above 80%.
