If a player has played 30 hands it's not possible for them to have played 27 of them from EP (early position). How many players are at the table? Is this a regular table or a fast fold table such as Zoom? If a player plays 30 hands on a regular 6max table then only 5 of those will be played from EP and it will be potentially less than that if any of the hands had 5 or fewer players dealt in - see
this guide for how positions are recorded in PokerTracker 4. Also on fast fold tables where players are met randomly then the positions you see them in will not run in a fixed sequence.
