Thought Downloads: Writing or typing?

I’m wondering if there’s a difference between hand writing my thought downloads versus typing them in to a blank document on my iPad? Will I get the same results from both? Or is hand writing them out better?

In the model.pdf document found on the Start page, it says “A thought download is a five-minute writing assignment. You can download all your thoughts in general or write your thoughts about a specific problem. All you have to do is put pen to paper by free-writing one sentence after another.”

Which makes it sound like it should be done via hand writing, but I’m wondering if there’s a science-y reason behind this?
