Most people come in for educational or career guidance, but I think it's best used as a way of understanding how your mind works, especially in relation to others'. The on-the-flying reasoning isn't pitted against good memory (there also isn't a single "memory", but we have different strengths for remembering words, stories, ideas, shapes, faces, numbers, melodies, and rhythms), but against a more methodical and well-prepared presenter. The on-the-fly reasoners are also quicker to see patterns and make connections among disparate data. It's great for trial law, but not so great (or distracting at best) for tax law, where you can't just wing it.
