A few days ago I was asked by a fellow diver some questions regarding air consumption and etiquette, your opinion will help to have a consensus.
Case 1
After planning for group dive (charter type) 1 hrs long, being an air hog you find out after 30 min that it would be wise to start surfacing (700 psi). Your choices are to signal the divemaster and abort everyone’s dive early or switching to the divemaster octo and share +10 more minutes of air (which you are not 100% sure you like). A third one might be surfacing alone or with your buddy.
Case 2
After some dives, considering your SAC, nitrogen, etc you find out your max dive time is 45 minutes. The dive group is planning a 55 minutes dive. What to do? Abort the dive at your 45 min? prolong to 55 min and make a deco stop? (the divemaster is aware of your time limit)
