Narrative:

Flared and leveled off a little high, floated, touched down approximately 3500-4000 ft from approach end. Normal deceleration and exit at runway's end. Runway had a slight dip in elevation it would be nice to know runway drops off in touchdown area, but since it rises again at the other end not much total percent gradient to publish. Atlanta also has a similar runway. This was not a problem since runway is long approximately 10000 ft but it would be nice to know gradients (slope) in the touchdown zone.
