Perdix's AI, what they got right, what could be better

[KenGordon]

As an example of my point, I did a training dive to 140 for 13. I started my ascent on time and was showing 10 minutes to surface (as planned). It was a shore dive with lowish vis so I followed the contour of the bottom/wall. My ascent was too slow and I racked up an extra 4 minutes by the time I reached my deep stop. If I had followed my plan only I would not have realized that I had on gassed so much during my slow ascent.

Most reasonable planning software, including the Suunto one, lets you choose an ascent rate. When first forced to follow a plan that includes a 10m/minute ascent many divers fail to arrive at their stops on time. Planning with a realistic ascent rate is important.
