Nevermind, watching it on the big screen I see it now. You stop accelerating after you crest and reach 6000rpm in 4th. You need to stay flat on the throttle until the braking zone of 15A. Then you will appreciate the late apex.
(Please don't tell me that was foot flat to the floor from your upshift to 4 until after the second crest... You will have crushed by BRZ dreams....)
