How the systems multiply each other
Income per hour is load value times cycle rate, so every system feeds one of those two factors. Mining power and speed raise the cycle rate; cargo and ore tier raise load value; drone count raises both; evolution raises the ore values available; boosts multiply the whole result for a window. That is why the site's advice always starts with a timed cycle — the loop tells you which factor is cheapest to improve right now, and the income calculator turns the observation into a number you can compare after each change.
