Per my lawyer, if your 485 file goes to a Service Center, that did not process your I-140, the 485 service center requests a transfer of the I-140 file also to itself, and that process takes a random amount of time, per my lawyer, upto a month at least, and the 485 file meanwhile has good chances of slipping under the cracks. So there is an inherent delay in case of such transfers. It is better that your 485 be serviced by same service center as your I-140.
This conversation had come up with my lawyer at time of filing, because he said the lockbox might give to NSC or CSC in my case. He said 99% will go to NSC, but in rare chance it goes to CSC, there will be delay, because CSC will also need to get 140 file transferred from NSC to itself.
