In the next version of Abyss we will be offering alternate sets of the 3 standard A/B Pair arrays that will allow the user to decide if they want the deep stops to be added, and if so, in what manner. By choosing one of the alternative arrays, they will trigger 3-5 additional stops below the current deco schedule that would be 1-3 minutes each in time. The Other method would be your ascent in 1/3rds. Where bottom is at 300ft, and standard deco begins at 100ft, the user would get an artificial stop at 233 and again at 166, both for a minute or two. Bruce Weinke just sent us some updated RGBM code today, so there may be some better bubble modeling as well in the tissue model, and we will be adding a full RGBM Algo (non-Tissue) as well. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Christopher M.
