I assume you are refering to deco software in the unit, and, IMO, herein lies a big part of the problem. You really shouldn't need anything more than a basic set of tables to dive trimix Rebreather. If you need the software in the handset you shouldn't be doing the dive, at least not before you have mastered it on OC and tables.
No, I meant on your PC. That is, the program you use to plan your dive and print out your tables. You are right, courses use tables only, but for Rebreather Trimix one really needs the program to do proper planning and get a safer dive.
There is a bias in my response: I believe all divers should include 10 hr tissue compartments for bone. My joints spoke to me on that one, and quite a few colleagues have the same grief. There is a lot of research done on this, published, but it has not made it to the tables used by training agencies, and with rebreathers dives are often much longer than for O.C., so this issue becomes a real one.
