OVR Calculations for VSA

The OVR calculations for VSA seems to use the average of OVRs for all lineups rather than just the OVR for the current lineup. I created a lineup that had a lower OVR than my usual lineup as a casual PVE lineup to use for event matches against the computer and when I played a VSA match I noticed I had worse chances than my opponents when my team OVR was higher than theirs. I couldn't figure out why but I remembered I created this lower rated lineup and tried deleting the lineup. Once I did, the chance calculations worked as normal. This is a bad bug or if an intended feature very bad for VSA. It doesn't allow players to experiment with different lineups and forces them to only have lineups with their highest OVR players.
