Summary
Since 2018 I have always answered no to the question are there any "super" armies in Art de la Guerre (ADLG)? After the thorough statistical testing described here that's still the case, but for entirely different reasons.
Until today I thought, given a high enough number of games, any variation in army performance (efficacy) could be ascribed to the inherent strength of the list and nothing else. That's not the case.
Chance genuinely evens out, and what is left behind is real and not chance - but that leftover is a tangle of list strength, player skill and popularity. The statistical tests only measure its size, but cannot pull the tangle apart. This applies to all the data I have available. More data will not help.
The answer is definitive, but it's case unproven. Therefore this post is the final piece to look at the issue of "super" armies in ADLG. Time to move on.
Those of a statistically nervous disposition read on at their peril.
