I dunno why, but in particular when playing WipEout, I never set an expectation based on who i'm playing for where to finish in the pack. You're going to have slip-ups no matter how good you are at the game, in fact the slip-ups are what make WipEout interesting. It allows me to see where i'm going wrong and the rough patches there are. For most games there can be "masters" but in WipEout, I see "Legends" and "Veterans" the day WipEout becomes the kinda game where you can be flawless is the day it loses it's magic for me.
Of course, this is just an opinion. heh. :D
