Well when you do averages eg:Ao5, Ao12 etc... Because I use chao timer an app for the iPhone for my timed solves, should I reset the session for every time I'm finished. If this is not the case how do the Ao's work then if I did 12 in a new session if I achieved my best for an Ao5 in those 12 does that work, or can anyone just give me the right rules or guidelines as I don't want to cheat myself as I achieved my first sub 40sec avg in 5 weeks of starting
