depedns on allocation and demand obviously. they get all the applications in, then sort them by average number of loyalty poitns per application (i say average number because you can apply in groups and they take the average between the individuals) and then mark the cut off point as the allocation.
I'm pretty sure (99.9%) that they don't use the 'average number' system anymore. They now work it on an individual basis and only give tickets to those within the group application with the sufficient amount to meet the cut off point, the others simply don't get them.
This is a much better system, as it means you can still apply as a group, with people with far less points than yourself and not worry about not getting tickets due to the average.
