Any chance we could get this mod to match configuration changes made to belts? I even tried to edit it manually but I can't find in the code where the speed of the belt would be decided.
I think SchallBeltConfiguration changes the belt speeds in config-1.lua, but there might need to be changes made elsewhere as well. It happens during data-updates, so a simple fix on my side would be to update the belt speeds during data-final-fixes.
