IssinryuKarateGirl,
I don't mean to sound like I'm disagreeing, because I'm not, but I don't think that's quite what we said.
You are completely correct that what you put in, you get out. No argument.
What we said, though, was that alive training including sparring is integral to one's ability to "use this stuff for real." Alive training means that skills are introduced, whether individual or (eek) in patterns, and then drilling which is unchoreographed, with realistic attacks and improvised footwork and timing, is done to build the skills in isolation. Following that, the skills are integrated into sparring so that they become a part of a person's usable skillset.
Training with aliveness (in the Thorntonian sense) is the key to making the skills usable. The isolated [alive] drill portion is the fundamental element in transferring moves from dead, cooperative, or solo training to usable sparring tactics.

Best,
