This is the tonal chart which I did today. The squiggles to the right are an experiment where I dipped the pencil point into some water before drawing. Now that it has dried, I can't see much difference! I also did a test where I drew onto wet paper, this dried leaving a sort of discoloured area around the pencil line. On moleskine paper this effect doesn't seem to work that well.
Soon I shall try to use the pencils properly, but when I do it'll be dry, or wet on dry - possibly wet point. I certainly won't be doing dry on wet.
