As somebody mentioned earlier, we continually monitor the effect that any restrictions imposed to protect "our" sector are having. If, due to staff shortage or temporary airspace constraints, we are relying on these slots to even out the traffic flow, we are still mindful of the effect on the users. For example, if the restriction is causing an average 20-30 minutes of delay, then an aircraft picking up 90 minutes will stand out "like a sore thumb". If we are the only restricting sector, and often we aren't, then it is likely that we will attempt to "take an extra one" to prevent some customer being penalised excessively. I thought we were being proactive and helpful. It appears from the tone of this thread that I am just being a nuisance. Perhaps I should let delays just "take their course" without trying to help? Comments please....
