The 24-hour limit IS the limit for a single dive. The 1.6 is CONTINGENCY and not NOT for planning your dive. You will be dictated by NDL, not O2 clock regardless unless you intend to do decompression dives. Theres a REASON why they tend to do 1.4 for MOD calculations and 1.6 for CONTINGENCY ONLY - safety.
If you want to go test if its fine to dive to a pO2 of 1.6, well deeper than your MOD for 45 minutes, go ahead, youll probably be fine. Just dont blame me if youre not. The table also dont say that youll die if you do, it says you shouldnt do it.
Gas planning might say you will die though - even with 40% a pPO2 of 1.6 would be to a depth of 30 meters and my 0,5 cfm/min SAC says id need 90 cuft of air just for the bottomn time, for me alone, with no regard of the descent, ascent or any buddies..
