Vortex Delivery UPPER LIMIT?

I've been considering the theoretical upper limit of shapes delivered simultaneously to the vortex in Shapez 2.

It seems that the more cars I put on each train, the faster the shapes can be delivered, meaning that in the last stage before delivery, the amount of lanes fed into a train has no upper bound. This would mean that the upper bound of shape delivery is equal to the rate of cars that can move through one space.

Since the fastest a train can move is through 200 spaces per minute, and 8 train lines can be delivered to the vortex at once, that means that 1600 train cars can move through the vortex per minute. Each with 540 shapes loaded onto them makes 864,000 shapes per minute. 14,400 shapes every second!

This is obviously a theoretical bound, because this would assume a FILLED train of infinite length. But, I've noticed the more lanes I add to this vortex delivery train, the closer I can get to that bound.

Just wanted to share my thoughts while I try to break the game How many shapes have you been able to feed the beast at once?
