BMD, my understanding is that SkyTools can import 2 MP element files from the MPC. The full file MPCORB containing all of the MPs that the MPC currently has, ~1.2E6 objects with the epoch 2022 Aug 9 00:00 UT, and the NEAs at Today's Epoch file that has all of the NEAs, currently 29,792 objects, with the epoch at today's date. There's also the ASTORB option & several other files from MPC as well.
I don't think that ST4v makes any changes to the epoch of the MP data file. It just uses the date provided. That date doesn't affect the calculations, it just indicates how reliable any calculations made using those elements might be. Old elements = less reliable. ST4v will complain if the elements are too old for that reason.
It's much easier to work on ~30k objects than 1.2 million
