The reason I asked was a recent V-planner profile called for only 1 min of deco at 10'. That and your comment led me to wonder if DecoPlanner/DPlan, as a GUE product, deviated from that and would always call for the three minimum stops you mentioned.

Others have posted that DIRF doesn't really cover on-the-fly NDL calculations, and that Tech 1 or Cave 1 is where that topic is covered.
How is the course content currently split up?

My first DIRF did not cover on-the-fly NDL calculations so i doubt the one that starts tonight will...

We were not shown on-the-fly NDL calculations in my DIR-F class. As a matter of fact, we were quite plainly told to keep diving our computers in computer mode, but definitely integrate the DIR dive planning tools we learned in the class into our diving. For example, the 1 minute each at 30', 20' and 10' will violate some computers (like my Suunto). Sonya said to just stay at 10' until the 3 minute stop on your computer is up, which is what I do.

Actually Decoplanner, even though it's a GUE product, is simply a deco program. Many of the things we do are not reflected in the program. For example, many of use feel that the times given for decompressing from Helium based mixtures are inaccurate. This has to do with the fact that the program relies on a standard decompression model.
The program is still very useful, but we only use it as a tool, not as a bible.
