It's easy to be that fast if what he's dropping are one liner posts but if he is looking to catch the eyes of the campaign owners, I feel more effort should be added and less of the post bursting because that is something most campaign managers actually frown over; post bursting.
Again, it's not an issue if you are quick to drop your posts but often times it's regarded as rubbish and meaningless. No need to be in a hurry to complete your post count when the CM probably gave you ample time to finish up.
