"Caveat: The  Catch-Up Point calculation assumes that the player collects all resources from the Gold Mine without allowing it to reach its storage capacity, as resource production ceases at that point. This is more of a concern at lower levels where the capacity is limited and  Time to Fill is relatively short. 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 last sentence of this caveat is completely backwards. If you are unable to collect regularly and your mine hits its maximum capacity, the mine stops producing gold, and therefore EXTENDS the Catch-Up Point instead of shortening it.
