I agree with you and applaud your approach. I like tables and the eRDP thing just doesn't leave me with the warm fuzzy feeling of tables.
I need to study the Wheel. There's something there to learn and I need to get after it. One of these days...

Actually the wheel is being "obsoleted" by the erdpml. There were always precision problems with the wheel as demonstrated by the fact that during the deco theory exam in the IE it was always briefed that if you can show the examiner how you properly got your "wrong " answer on your wheel, you could get credit for a correct answer. The erdpml elimininates the mechanical discrepancies.
