The passage around this formula
A threshold stated only in words is not yet a threshold. Matching the paper’s own design choice of N=40 trials per architecture per condition [ 1 ] keeps any comparison directly comparable to Table 1’s published rates and gives roughly ten percentage points of resolution on a proportion near the middle of the range — enough to separate the illustrative 0.90 and 0.13 ratios above by a wide margin, and enough, at that sample size, to distinguish either from a genuinely intermediate result using a standard two-proportion test against each architecture’s own matched-appearance baseline rather than an eyeballed gap.
