Except you have to bring the Fleet carrier out there first, which is slower then jumping out anywhere in a decent ship.This is probably for dealing with 1st time discoveries.Imagine go to an area that is undiscovered and sell all your data quickly so no one else will have the possibility to get some first discovered systems there.It's not game breaking but unfair in some circumstances, unless FD manage to find a way to sell 1st discoveries bonus to the first who gets to a star port
So I still don't understand this.
