Table 1 Reliability (\(\mathcal{R}\)) under parallel attack. Each row corresponds to a different 〈n,f〉 system. Each column (below the top merged cell labeled \(\mathcal{R}\)) corresponds to a different MT τ, normalized to the ETTF of the reference system 〈1,0〉. The values of desirable reliability (i.e., those that are higher than the reliability of 〈1,0〉 for the same MT) are highlighted in slightly larger font size
