Players change how he/she plays all the time.
With that said, how old should an opponent's hand history to be considered a valid representation of his/her current playing tendencies ?
Should I be deleting HH that are 3 months old, 6 months old or 1 year old ?
I'm not concern of DB performance or DB size but more concern about the stats of my opponents being an accurate representation of how they currently play.
