I’m not talking about a limit on how much DP you can have, I’m talking about the daily DP gain limit.
In the above quote from the post Mathematics of the Economy, you’ll see that within a period of 24 hours, everyone can only gain so much DP. Extreme wanted the cooldown to reset every day at Noon, but that can’t happen since everyone has different time zones. Extreme implied that he thought that once you reach the limit, it took 24 hours before you can earn more.
Well, it’s more like a soft limit, from what I understand. Once you gain 5k DP in a day, you only are earning 5% of the normal DP. It would be really hard to reach the final limit of 10k.
