Uplink Utilization %

ePMP Firmware 3.0 we still see SNMP ulWLanTotalUsedFrameTimePerSecond.0 and webUI Monitor->Performance still show essentially 100% uplink timeslot utilization at all times, about a year after first complaint on the subject here on these forums.  (which elicited a reply that it was a known bug that would be fixed in a "future release")

When will this be fixed???  We have sectors where I am certain we are (at least some of the time) hitting 100% uplink utilization.
