all it needs to be is auto save turned on play a bunch of games get a section of ten replays in a row. from the recent set. just to provide a snap shot how you played at that time. if you want to play around with the way you play that's fine. ten is only a small sample size so its not all encompassing. and i was only planing to do a surface look at it to start with. just to see if this is any good?
