what was fascinating to me was how I fitted into the MUST SHOULD MAY MAYBE-NOT DONT matrix (in pseudo-normative form)

I used all but one of the MUSTS.

I used a few of the SHOULD

I used a similar few of the MAY

I only used one of the MAYBE-NOT (pow, and I am doing base arithmetic but not crypto)

I don't think I use any of the DONT

I'm interested in moving up on the SHOULD and MAY
