ADL: mismatch between AD4 and vina resuts

Presumably, at least one of the two results is wrong. The Vina FAQ
explains how the binding pose could end up being incorrect (and almost
all of the possibilities apply to AutoDock 4 as well).

When I tried using vina, for the same grid box parameters, I obtained a B.E of -9.9 and the position was very different from my AD4 results. why is there a discrepancy between the results of AD4 and vina?how can the binding energy vary so much?
