Scientists are typically pessimistic with unknown variables and there may have been other forces at work that added to the effect. They’ll study the results plus the ESA is sending a follow up mission to the asteroid which will add to the data. There’s still so little we know about asteroids it might not be a bad idea to do a dart 2 with a lander to examine a different type of asteroid interior more closely.
