Seeing information on a Human Design chart is different than reading that chart to the person asking for it.
I mean, what you see on the chart is detailed information whereas what you're meant to convey to your client is the synthesis of their chart. And the synthesis is more than the sum of its parts.
Yes, you begin your preparation for the reading with an in-depth analysis of the chart, but then you have to stop and let the chart "talk" to you. Somehow you have to "breathe" it, feel its frequency, in order to look at it from a different viewpoint.
And that's when what you see, more than the single elements, is the whole sentence where each element finds its own place within the whole.
