being a natural is just about feeling the vibe -calibrating if you want- and knowing when to apply certain canned stuff or not. in other words, naturals are more flexible since they can feel when it is appropriate to improvise or easier to use a routine. in a way, a natural is still being spontaneous when sometimes using canned stuff because it wasn't his plan in the first place.

the 'hi-analogy' kowalski used earlier makes a lot of sense! its about knowing when to say 'hi' instead of 'bye'
