My understanding is that at the beginning of the year they are told that they have N allocations for whatever. For vettes, it is Coupes, Verts or Hardtops (Z06). Each month or so they get a report that shows what they get from their allocation. In other words, they don't have control over when they get the owed allocation.
I'm sure others will be able to make this more clear.
