Please listen carefully:
The bottleneck is in the pcb production.
That means whether ED can assemble 4 Pandoras per hour, or just dumps the parts into a box, or just takes a dump in a box, you would not receive your Pandora sooner.
The ONLY instance in which this could possibly make a difference in delivery date would be if the boards were delivered to OPT in larger batches than could be handled in a day. Unless the rate of pcb production exceeds the rate of assembly, the impact would be incredibly minor at best. Ya might save a day, maybe two. That's assuming they never flex a workday, always build and ship immediately, and by and large manufacture Pandoras like optimized robots. Since instead they're human and would hold to a ship-within-7-days guarantee, you would not receive your Pandora sooner.
