so i did some testing on the following Setups:
- Inserter UPS Difference.jpg (22.61 KiB) Viewed 1922 times
The Filter-Inserter on Top is unloading to Blue-Belt, the lower one is unloading to an Underground...
To see what's better UPS-wise i build two Setups with 10.000 Inserters each. All the Filter-Inserters are clocked.
RESULT
It's better to unload on Underground-Belts. The Setup unloading to Blue-Belt gets me to ~115 UPS maximum and the one unloading on to the Undergrounds ~120 UPS.
So feel free to see it yourself with the Savegames attached to this post. (You wanna sit in that Locomotive and Zoom all the way in to get the best possible Comparison between these two Maps)
That's all,
Cheers!
