How can you get something faster if it is being sold off to someone else under your nose and then you remain in the queue? Its like going to a deli and taking a ticket and then the shop assistants friend comes in and jumps the queue. YOU DO NOT GET YOUR SALAMI FASTER!
I understand the extra revenue will be used to hire more employees to assemble pandoras quicker, but this does not in any way mean everyone will get their unit faster at all. It just means somewhere down the line you will be able to produce more per day. So somewhere down the line it will increase the speed, but for those that waited longest it means an immediate delay.
At any time a queue jumper can jump the queue and if there arent enough parts to fulfill a two year old order well thats just bad luck 7 day premium pandoras have a higher priority than the customers who waited so long with no sign of any progress on their order at all.
