Fartsock and other QF's,
What will work when you come onto 132.2 (can't speak for the the other freq's, perhaps an ATC from the others sectors could contribute??) is:
"Centre, QF... speed on descent 265kts, estimate Narel..... unless it affects our slot in the sequence or slows the aircraft behind we can descend at 300, 320kts etc, new estimate for Narel......."
Believe it or not even 1 minute later at the fix can shove you back 5 to 10 (or even more) minutes in the sequence.
