I have a game I am playing that I can spend units (explanation would be complicated) to earn units faster. My growth rate depends on the number of units spent. At the moment I am growing at a rate of 1/100,000 units per second. There are several increase options:
- Spend 1 unit to gain about 1/1,000,000 increase in growth rate
- spend 4 units to gain about 5/1,000,000 increase in growth rate
- Spend 30 units to gain about 50/1,000,000 increase in growth rate
- Spend 50 units to gain 100/1,000,000 increase in growth rate
As it takes just over 1 day to gain 1 unit, is it faster to spend 1 unit every time I can or to save for 4(ish) days and buy the larger? Or even save for 50+ days? Does spending early cause a faster increase then spending less?
