Nice calculations but I am not as concerned about a buddies air consumption rate as if they are a safe and good buddy. I have a 5’ octo hose and my buddy typically takes it for 10-15 minutes every dive. Gives us both practice with regulator exchange and still lengthens our dive time. I’ll dive with a newbie as long as they don’t stray further than a breath away.
