Small text because most people don't like reading the math about video games.

I spent far too much time with the Focus capacity increases. Put all the current data in a spreadsheet. "Best linear fit" didn't yield believable results.

However, the delta of delta capacity cost did. Example: The cost to increase capacity from 12→13 is 21714, 13→14 is 23733, and 14→15 is 25782. The delta (change) in capacity increase between 12→13 and 13→14 is 2019, while the delta for 13→14 and 14→15 is 2049. The delta' ("delta prime) is 30.

Using the rest of the values, the trend of delta' is within 3 of the previous delta'. A little goalseek, seeing the trend of a diminishing downward slope in delta', and you have your future answers.
