The exact stat isn't in the article I linked to above, but I saw in a magazine at the airport today, these details about the “commands” issued from Ground Control to the spacewalking NASA astronauts who were working on the space station:
1631 different commands were issued, over the course of almost seven hours. A normal spacewalk involves 200 commands.
Think about the level of detail in your standard work. Pretty amazing that they could plan something and detail it into that many steps, isn't it?
