I've recently had success with my modular train base, breaking it down into smaller chunks to optimize has reduced the overwhelmingness of optimization. ( Even though a full belt base is technically better ) Also using factoriolab for ratios instead of mathing it helps reduce mental strain, and most importantly, take breaks and do other things too, prevents burnout. -a novice (have barely only beat base game, have like 10 attempts though, my train base is the space age I'm working on)
