The prediction errors in the two cases are quite different. The prediction in the minimum-delay case is almost perfect. (Note that the prediction indeed would be perfect if the operator were infinitely long.) The difference between desired output and prediction is almost entirely in the unreachable range, which occurs before the onset of the wavelet. In this case, the difference is essentially the advanced head of the minimum-phase wavelet, where the advance is equal to the prediction distance. The head is substantial because a minimum-phase wavelet has most of the energy up front.
