Thanks DP.
So as I am a bit fick,
What you are saying is.
As soon as holding is mentioned, slow down immediately to holding speed (we will not lose our place in the queue) and when we do make the fix the delay should (subject to the info from your supervisor being accurate ;-) ) be what you are telling us. Whether the words 'total delay' or 'expect 10-15 mins in the hold' are used - it makes no difference - they are the same beast.
I will try and convey that to the people that I am flying with as there are a lot of theorists out there!
