My stats for Stars are reflecting the results for only the time I am sitting at a particular table. My opponents stats are reflecting their aggregate history in my db. Is this what I am supposed to see in my HUD ?
Yes, your self stats are for the current table session (much like PokerAce Hud) whereas your opponents stats are their lifetime stats. If you need to view your lifetime stats, you should do so directly in PokerTracker.
