I am aware that the ROT depends on many factors, however on my last shift being bored in the tower I timed 10 landing to see how much time they spent from passing above the landing threshold until all of the aircraft was past the holding point. The quickest made it in 1:37, the slowest took 2:23... And that was using RWY 31L, with most aircrafts vacating via E8.... so there is room for improvements I would say.
As for our LVPs they are quite a bit too difficult to explain quickly (I believe out LVP rules are a 38 page document...) but quickly explained during CAT 3B operations we have a landing interval of about 7 minutes, add another 5-6 for each departure in between. If we refuse traffic is is probably either because you want to divert here when we already have traffic holding (you would have to go to the back of the queue if you did divert), you want to depart from one of the UAE airports (no point for you to get airborne to join the hold for 1-2 hours), our aprons are full or you are supposed to park in one of the aprons that are not CAT 3 approved. If you were refused for any other reason that that, feel free to pm me, and I will try to explain to you.
And the follow-me is being used if there are any equipment outages, but I still believe we can have about 8 aircraft taxiing at the same time, so single aircraft operations are not the case as far as I know?
BlueSky, nice to know, I have told my colleagues about this, and I think we will see a bit more holding in the time to come (our 8pm inbound rush is starting to get silly anyways with traffic being vectored almost to Al Ain before turning base). But just out of interest, how can you give me extra spacing for the ATUDO arrivals?
