The actual reason you double is because the sim says to double. Often you can figure no logic to why a move is right. You don't need to understand why. You just need to trust the data. That said, soft doubles are based on the dealer bust probability as much as the chances of you getting a strong hand. Note that you only soft double on hands that the dealer is more likely to bust.
