There are 4 Time Warps upgrades, one being a one time purchase. The reward from Time Warps does not factor in the profit from Flux Capitalors. There is a formula, which tells exactly how much cash is actually rewarded from Time Warps:
- $ d = x / (1.21y + 1) $
Where x = Time Warps, y = Flux Capitalors, and d = days of profit.
