Hm is that the hidden discord channel? I think I have access to that. And no, higher LPE does not necessarily mean higher ROI. ROI is still bound to prices on the market, what one can get for their money. For example, if I change my Simulation to GF instead of RF:

Beta Rare Gold foil. I pay $220 for a max, giving me 20,000 PP. That is 90 PP/$.

My buy-in would be: $2200 (10 max cards) + $50 Plots + $10 Cores + $100 Stake = $2360

Grain plot still feeds 4 workers, but 20,000 PP have to be fed (200 Grain/h or 1,979 DEC/h).

Stone production will be 200/h, minus 10% makes 180 Stone/h, which is 27,127 DEC/h, minus 1,979 = 25,148 DEC/h, 603,552 DEC/day, 220,296 DEC/year.

ROI: 220,296 / 2,360,000 = 9,3% per year (vs. 12,1% with Rare Beta RF)

BUT LPE = 25,148 / 2 = 12,574 (vs. 3.501 DEC/h/Plot with Rare Beta RF)

So, the yROI of my simulation goes down, but LPE goes up substantially. Hence, higher LPE does not equal higher yROI - that if I calculated somewhat correctly here :-D
