I have seen such detailed and tidy whiteboard diagrams, but the catch is that they never occur in active discussion. It doesn't make room for scribbling, and stopping a discussion for 5-10 minutes to draw slowly and nicely doesn't make sense...

True, no one can understand my whiteboard drawings the next day, not even I.

Perfect operational security!
