UnRep times:
To calculate a [rough] unrep you need to know factors:
By UnRep operations at sea you got 2 possible transporting options:
1: by cables between the ships
2: helicopter shuttles
What I know about transportation by cable is that the sea must be relative calm; the ships rolling during this operation due to the displacement and speed of the ships so close to each other [about 10-20 meters].

The transport between the ships by cable line is relative slow. Electro engines or people running the cables. So it takes at least minutes to bridge the distance between the ships, but you must also calculate time to click on/off the payload from the cable line and make room for the next load. There is of course a maximum weight that can be handled per single shuttle. And do not forget the safety/safety protocols…… You cannot say “Oeps” when a container splashed into the water.
The navy uses helicopters to transfer ammunition from the support vessels to the receiving ships.
Transferring these crates and containers by helicopters goes much faster, but, just as transferring by cable, there are limitations as well:
A helicopter can carry limited weight
They transfer 1 or 2 items at the time, I have a collection of photographs showing UnRep operations; on all pics you see the helicopter carrying 1 item sometimes 2.
The smaller the receiving ship, the longer it takes, due to limited space [helicopter deck].
The metrological circumstances: UnRep a vessel in stormy weather takes much more time than when it is a calm day.
This is my 1 cent contribution for now. I personally doubt that the transferring time per item is 15 seconds.
