Hi,
in the class:

pgenerators/EvtGen/EvtgenBase/EvtStdHep.cc

you can find that the precision is set to 4.
If required one could even improve it and put it to 5, but I think the difference is neglibigle for our eyese. An approssimation of about 0.1 MeV is completely covered by our momentum resolution, at our scales.
If you can prove that precision 4 could give us problems and that we need to move it to 5, then this modification could be easily done.
