Similarly Eq. (9) will be labeled “the approximated formula or expression” because one cannot recover the exact Kubo–Greenwood formula from it by simple substitution for the delta function.

Let us compute the Greenwood and Peto intervals at time t3 = 5.4. For the Greenwood method, we must determine V3 first. We will do this using the recursive formula, first finding V1, then V2 from V1, and finally V3 from V2.
