Ranking is the actual measure, not the nominal working fitness. If we just look at 1000 trials, comparing the actual rank to the expected rank, a perfect fitness signal will have a St.Dev. of zero; 1,2,3,4,5 ...
Ranking of random fitness has a St.Dev of about 410 from the expected rank. Using (1 + k / 1000)÷Rnd the St.Dev between the expected rank and the actual rank is about 320-350. A very weak signal.
This is sorted by Working Fitness. What was ranked 863 is now first on the list.

Of course, there are many other sources of noise that dilute the fitness signal, but this is the most egregious departure from model realism.
- A different run than the previous. They're both typical and should be easy to verify.
