I think the AIP says someing like "must be flown as accurately as possible", there's certainly no 10 knot tolerance as far as we're concerned.
Just as an aside they've changed the rules for 2.5nm spacing and we're now going to be able to do it much more often than we have in the past. There's no tolerance though and in theory if we get to 2.49nm on the approach we've lost separation and should be suspended and investigated.
So, if you chaps and chappesses keep fiddling with the speeds yourselves and separation gets lost on final, don't be surprised if delays build up quickly because there'll be nobody left available to work...we'll all have been withdrawn/suspended!
