One of the reasons I created my own Excel dive table from NOAA tables was because I'm cheap, have a sick fascination creating tables in Excel and like to get something back for my tax dollars.
Speaking of which, I downloaded the 900+ page US Navy Dive Manual rev6. One thing that caused me a double-take, was that the Navy air tables are more conservative than published NOAA tables, especially on long shallower dives. I'm beginning to think that those safety stops are more important than people know. I checked the Excel Dive Planner and it matches NOAA, but not NAVY rev6.
Also, the Navy Nitrox "Working Depths" are shallower than NOAAs MODs too. In part because they state that too many repetative dives using nitrox above 1.6 partial pressure will eventually take a toll on your lungs. In fact, repetative dives are not permitted if the first dive pushes 1.6pp. Their EAD tables are supposed to be based on 1.4 pp, but it looks like their "Working Depths" for Nitrox seem closer to 1.2pp. It'd be nice to have a dive planner where you can fiddle with all this and make it fit the tables you want.
At the end of the day, I'll be trusting my dive computer, but a good dive planning tool is certainly important.
