"“this is where you get immediate feedback that will make your model more specific and accurate”" Sure, break the process's down that you are trying to model.  So when you are using the person who exhibits this skill, practice immediate sequences of behavior, emulate what you perceive on yourself.  See what sort of feelings, visualisations etc.. you might get from this...notice the differences..are they significant!  Find a way perhaps to test this sort of immediate performance, so you can measure what the other person is doing and you are doing.  If you feel like you aren't getting anywhere, try something different and then see if you notice that in the person with the skill.  Notice the effects, the differences..   Keep up this cycle and you can learn a lot.
