I share the same opinion. Asafa’s run was his best this year. It seemed at one stage he was catching up with Gay and then decided to let go. Maybe I am trying to see too much into it but I get that feeling when I watch it. With a good start and slightly better drive as well as longer top end phase he just may be where many of us want to see him. Gay ran his “usual” maximum. IMO, I do not think Gay will go any faster in Berlin. Though it would be nice to see all three of them going sub 9.70
