Is there a different degree of acceleration between PACE and PPH?

No. Under Early Certainty from Search (ECfS) files processed via PPH or PACE are both treated with the highest priority. In the context of the PPH, the degree of acceleration may vary depending on the individual circumstances of the particular case, such as the usability of the OEE work product, the point in time when PPH is requested.
