Ingemar FWIW, I am diving the 125 algorithm with no safety other than the following: 1. I insert a 30 m deep stop for 2 minutes (planned into the profile). 2. I plan the dives as sea water but my instruments are calibrated for fresh water. 3. I leave the bottom 1 minute before the run time of my tables. Most of my Trimix dives are in the 60-70 m range and I have had no problems. I originally ran with tables that resulted in similar deco and run times to Proplanner with 10% safety factor (roughly equivalent to a 5% extra N2 loading in the Abyss), but decided there was too much safety built into the combination of the tables and my execution of the dive. I believe a slow ascent is important hence the deep stop. I prefer to add the safety into my dive execution - leaving one minute early can be equivalent to 5 minutes in run time and this is safety is more than would be the case of a "typical" safety factor calculated in the tables. I see no need to add safety into the tables and also into the dive execution - but this is the choice of the individual. At the end of the day it comes down to individual responsibility and awareness. I have to say that I have not yet done sufficient dives or multi-day diving on these tables to be sure that these are good tables for me. As for anyone else, then that is down to the individual.

What algorithm are you using and do you do any adjustments to get deeper stops?. I have used Abyss 125 for quite some time now, the 150 have in my opinion to long deco times. Have anyone used Abyss 100 (strait buehlmann) for trimix diving?. The dives that i do are in the 60-70 meter depth range on Trimix.
