Without phase detection there is simply mo way to predict focus without trial and error. this involves something analogous to a binary search. The lens must sample a couple of distances, choose the better contrast of the two, more restrictive sample of a difference distances, choose the best again, ultimately converging on the best contrast inside the focus box.
