Well, if you figure out where to start, ask away. The problem I have with numbers is that I agonise- is it really a 6, or is it a 7? Without a number to point at, I can't do that- I can only say "I feel about here" and look at previous dots- and say "I feel a bit better than yesterday's dot". In the end, trends matter more than if I pick a 6 or a 7.
