Today after 40mins at 60-65m and having ascended to 40ish m. My buddy bailed out on to a Ali 80 of 18/45(I believe) and at 21m on to a 7ltr of 50%

With 50mins of deco left to do @6m the 7ltr was down to 60-70bar.

The drop tank of 70% was all but emptied to complete the deco.

No drama because we were on a deco station surrounded by divers and gas and the drop tank got to us no problem.

No station no drop tank no buddy he would have missed some deco.

The morel of this tale is there IS no answer to the question in relation to depth inlet. The answer has to relate to logistics diving conditions proposed run times and SAC of the individual diver.

My buddy had perfectly adequate bailout today but on the same dive with a free ascent in worse viz, it might have been a different story.
