A suggestion from someone to the east of you guys...
At the start of each hour, about 5 mins in, give us a call to see who answers. Depending on the answer (I'll leave that up to you to decipher) you can then ask for 10/15/20 through two certain gates and you WILL get it, 99% of the time treating the two gates as one. We love to sequence, but we also love to know if the b.... hold will be used as we can then keep the arrivals high and not play too much with their speed. But don't get too used to it as the ranks here are thinning fast (to your benefit manning wise).
Three with their resignations in, and several more waiting for the opportune time to hand theirs in ....not that resignations are needed as new contracts are yet to be seen.
