The idiotic system adopted by ATNS/CAMU was developed by IATA. So yet again IATA is trying to rule the world...Does this ring a bell? as CP mentions, money has been spend, and now has to be justified... So DO WE SUCK UP? Nah, not me, I'll keep moaning at ATC, merely due to the fact that you have to standby on "Delivery" until fully ready, and then call back "fully ready", well good luck trying to get a call in the early morning, even on your CTOT. Next thing that happens is that you have missed your slot, can we get a new one? Computer say no...P!ss poor try to get slots going for the "over estimated" worldcup traffic".
