In terms of GIMPS, stopping immediately after a factor is the efficient thing to do, (it's not prime, QED). Somebody might eventually extend factoring, but they're already "wasting time" (in terms of prime finding) so redoing a bit level is not unexpected. Primenet assignments are to TF from X to Y, or until a factor is found. Prime95 will not finish the bit level.
