Dody... Nitrox 32% means I get longer times to NDL and is better over repeated dives. However dive times still depend on your sac rate and how long you stay at depth. If I was using nitrox 32% staying at 30m depth for 24 minutes I do not exceed NDL and can ascend and finish the dive. If on air at 30m can stay for 15 minutes but that is then 0 NDL so for safety lets make it 12 minutes at 30m on air. Nitrox gives me longer time to stay deep. It does not change the sac rate. So on multiple dives where you want to go deep to 30m then you get longer times to NDL. Even when I dive with my friends are also good on gas consumption we do not push staying deep on our dives. Sometimes we use nitrox but leave our computers on 21%. Some DM guides will do this as well.
I am not sure if I understand the meaning of your answer... The discussion here is about the advantages of nitrox, and I think that @EFX (and others as well) said it right. If one has problems because of gas consumption, the **short-term** solution is not to avoid nitrox: it is to use bigger tanks! If the gas consumption is too high, the optimal **long-term** solution would probably be to reduce the consumption itself. But the advantages of nitrox are always there, so the details about consumption are off-topic.
Am I missing something?
