A 1/5th prime splitter configuration done in North South orientation.

NOTE:  It needs to be noted that this only works in north-south orientation because of the grid gap up and down gives issue when placed east-west

A 1/5th prime splitter outputs the product at a 80/20 % ratio, so you can send only part of your production down one line instead of needing perfect splitter or manifold each time
