The first week pays about eight times what week six pays
A shift pays out the same amount whether one rig works it or a thousand. Over 4,000 simulated shifts with rigs entering on a realistic adoption curve, the per-rig payout in the opening week ran 7.6–8.4× the payout once the floor filled.
Read the finding
This is not a bug and it is not a bonus we are handing out. It falls directly out of the pool rule: one twenty-eighth of the pool per shift, split pro-rata by ore. The numerator does not care how many rigs showed up; the denominator does.
The consequence is worth saying flatly. Anyone who buys in during the first week and extrapolates that rate is extrapolating a number that structurally cannot hold. The floor filling up is the mechanism working, not the mechanism breaking.
We considered smoothing it — scaling the payout with participation so early and late look alike. We did not, because every version of that we simulated either drained the pool in a month or made the first hundred players subsidise everyone after them. Both are worse than an honest curve.
