[Post completely revised from original version. It now includes all bonus progressions.]

Each bonus has three tiers--the cost and the benefit increase with each tier. When a bonus is used, it progresses the bonus to the next tier. Once a bonus has been used twice, all additional uses of the bonus will be at the third tier level.

Multiple different bonuses can be activated at the same time but only one of each bonus may be active at one time (e.g. you can activate both the PCI and food production bonuses at the same time but you cannot activate 2 instances of the PCI bonus at the same time).

Some bonuses have a limit to the maximum number of times per country they can be used (currently base explore rate, attack strength, and spy power).
