Based on the summary of computations below, the Catch-Up Point calculation assumes that the player collects all resources from the Mines o Collectors without allowing it to reach its maximum capacity, as resource production ceases at that point. If the player is unable to regularly collect and achieve the full potential of the collector, the Catch-Up Point is actually shorter and performing the upgrade becomes more advantageous.
The Catch-Up Point is the time at which the newly upgraded or the newly collected Mine or Collector has equaled the total production of the mine had it not been upgraded - this does not consider recovering the cost required to perform the upgrade.
