I played Superstar a lot in an arcade when I was a teen, but my memory for the replay levels is not "that" good.
Can't read anything off the pics in the ipdb, but one owner on the Pinball Owners site has a photo where you can make out his replay levels (100,000, 130,000, 160,000). Might give you a starting point?

You also might message a few of the owners on the Owners site and humbly ask if they have any knowledge of the factory suggested levels.
