To answer your question , I find the suunto dive log (downloadable for free) an
outstanding learning tool. You can simulate dives the way you want. They will be
shown graphically together with indications of NDL/Deco step by step trhoughout
the simulation plus a bar chart graph for the various compartments used by the
model. This graph is also shown at every step througout the simulation. Beats
any table by lightyears in terms of what you can learn.
