Elon must be drinkin' and tweetin' again.

From the video of both landing attempts I've seen, my theory is that they are retaining too much ullage propellants and so its both heavier and has more momentum than their control system is accounting for and/or, the fuel fraction that they do have available is to slim to both control decent velocity AND directional control. It is a very challenging problem.
