Women's LJ was a letdown especially given some athletes just couldn't give their best and the progression in HT by Katzberg is something different, but I don't know his backstory. Sometimes backstory explains large progression.
On the 7 I completely disagree: Brooks would have taken bronze if it wasn't for tripling out of LJ, while Vetter has shown she can sustain a better level just one year ago, lack of training could be issue with her. There is also the question of injury, especially with KJT. And then we have Sulek and USA can qualify a better athlete than Hawkins, who can surely get to 6700 if they are on form.
