90 D. Day et al. This means that the estimated value of λcan be used instead of the exact value and that q ∼c, which is the benign case. This is to be expected, since usually the approximation is quite accurate and the nonlinear equation is trivial to solve. Typically, γ 1. On the other hand, if δ > c γ, then it is worthwhile to carefully solve the nonlinear equation that determines λ; we expect that a ∼δ.
