Using V-Planner, put in your 10/50 bottom dil, and Air swap in ascent. Take a look at the ppInert graphs. See how the N2 inspired increases dramatically? You shouldn't do that, particularly on bigger dives. The best deco will come with a continuous reduction of each inert gas through the ascent.

I do not have a lot of experience with switching except to practise but it seems to be alot of hassle and extra risks to manage for saving a few minutes of deco.
Ross:
Can you explain how you ICB alert works in V Planner?
Can it be modified by the user? If so why?
Can you point us to any literature or reports in which your alert is based?
