Well, that's the estimation given by the book keeper 😬

Yes, and it is very misleading. It calculates straight line ROI, but clearly there is an exponential curve, the half life of the payouts (how long it takes for payouts to half) seems to be about 15 days. Which means, very conservatively, you will be lucky to break even in double that time, more likely it will be closer to 4-5x the time it estimates for numbers over 30 days.
