Just addressing the holding statement. After 26 years using procedural seperation, domestic and oceanic, I can yes. We use 20 miles from protected holding airpace. seeing most of our holding, blocks aircraft in airspace below 10,000 feet from climbing, 250 knots equals approx 5 min. An aircraft doing 120 knots equals 10 minutes. Wish we could have used 5 min on everyone.
