It is not, the Fischer connection is for live ppo2 monitoring connected to an o2 cell reading what is actually in your loop. The fixed set point is so that you can use it as back up on rebreather and bases it's calculations on a fixed set point that you enter on it. For example I run my CCR at a set point of 1.2, if I have an electronics failure I can bailout to OC and follow a plan on my fixed set point enabled computer because it will have been able to accurately track my dive to that point. As for the "I have no use for CCR so I don't care" point of view, many others do and that's why they are commenting and making the comparisons to other computers in similar price points that do have that feature. And for what it's worth everyone thinks that until they go CCR and then wish they had bought some upgraded gear.
Thanks for the clearification.
