Like I said before, the number to shoot for will vary as difficulty values get raised, barriers are broken, and limits are extended. Right now I believe Beth Tweddle of Great Britain has the highest start value on any apparatus-a 17.8 on bars, if she executes her upgrades cleanly. But I could be wrong. I have a feeling it won't be soon before we start seeing 8.0 difficulty values, which would make 18 the new 10. Especially if Nastia's hints at the 2012 Olympics turn out to be a reality. And if He Kexin keeps going too.
