If this was easy, I guess anyone could do it, exactly why I am interested

Now if you ignore any deco time less than a minute (blue columns) generated by Multideco you get a result close to Subsurface.
So this is a good example where Buhlmann is Buhlmann but not necessarily Buhlmann. I assume the programmers of Subsurface decided that any deco obligation generated that is less than a minute is ignored. That is why Subsurface has generated its NDL's which are a bit more than the Teric.
This is just one example where programmers have to make a call on their interpretation of Buhlmann. There are many more assumptions/decisions that will add to the variation of their model (including bugs) versus others.
@atdotde thanks for your feedback. Its always good to hear from the source rather than to speculate. In my attempt to match Multideco to Subsurface NDL's at every depth specified in the table above I had to add about a minute of deco to Multideco to match Subsurface. In both cases my descent/ascent was 60/30 ft.Subsurface adds a stop (of at least one minute as all stops are multiples of entire minutes) whenever otherwise you would violate a ceiling not matter by how little. But what Subsurface actually does when computing Bühlmann deco times is to take into account off gassing during the ascent from the previous stop.
