It gained exactly 2.3 HP from 5000-5700 and only 9.8 HP from 4700-5700 RPM so I wouldn't say it was still climbing.
He only posted lift numbers. Maybe Ramm is doing a mind squeeze on us and it's some kind of a low lift cheater grind just to make us go off the reservation. IMO, it's way down on lift.
From my experience, that power curve will make the car run the same ET whether you shift at 5000 or 5700. I'd like to pile another 50-60ish and run it to 6500 RPM.
