The minimum Accel. Alt is there due to obstacle clearance, the maximum Accel Alt equals 10min@TOGA
I really don't see a good reason reason to accelerate 130ft below the calculated Accel Alt, why go against something calculated by the Airbus Airport Analysis software? Might as well make up your own Vspeeds while you're at it.
What is the OEI accel alt for SCL rwy 17L? I hope it isn't 400ft agl.
