Abstract
We continue the theory of evasion and prediction which nas introduced by Blase and developed by Brendle, Shelah, and Laffamme. We prove that for arbitrary sufficiently different f, g is an element of (omega)ome ga, it is consistent to have e(g) < e(f), where e(f) is the evasion nu mber of the space Pi(n<omega) f(n). For this we apply a variant of She lah's ''creature forcing''.
