Sometimes you come up with true gems, Fern. I agree wholeheartedly. In fact, when I'm doing mentorship, I tell folks to treat the SCA as a painting. And much like a painter would 'sketch' in the horizon, or sun, or whatever - PRIOR to actually painting, I like to put adjustments in the grid just as placeholders. THEN I start painting (or analyzing). Sometimes it turns out those placeholders shouldn't be there, and - more often - it turns out the placeholder values are quite different than what I started with.
