Quoted from bkerins:Stamina matters: Pinburgh lasts 10 hours a day for two and hopefully three days. If you can keep up a high quality of play for a long time you'll do well.
Playing multiplayer games, against other players, would probably be my strongest recommendation. You'll get used to the rhythm of playing and not playing, and figure out what you do in the short downtime between balls. Watch everyone play! They're teaching you to play better, and their play gives you information about how a machine plays.
Good advice here, as usual.
This tourney sounds like a tremendous amount of fun. The ongoing match play concept is very cool.
Unfortunately, the stamina part has been the biggest deterrent for me/my son for attending. Being required to play at various times during the day, all day long is much different than, for example, an open qualifying format where one has the opportunity to play whenever they choose during that same time frame.
I prefer not to play early in the morning and my son prefers not to play late at night. Man's got to know his limitations 
I seem to recall KME saying stamina is a skill. He's right
