We define maximum “good” λ as the maximum value of λ that enables us to reconstruct the species tree accurately. Of course, the exact values of the “good” λ’s may vary from one species tree to another. As one can see, the empirical values of maximum “good” λ’s are much higher than the theoretical ones, dictated by (5) (approximately one order of magnitude)
