ℹ️
Work Efficiency Explained
Melange per Sand Efficiency: How efficiently you're converting sand into melange compared to the theoretical maximum (large refinery rate).
100% = Maximum possible efficiency (0.02 melange per sand)
Below 100% = Less efficient than optimal
Calculation: (Actual Melange ÷ Sand Used) ÷ 0.02 × 100
Concurrent Operations: Multiple refinery types run simultaneously. Total time = slowest refinery time.
