At about 60-70 feet, when deploying a smb how much air would you put into a 6ft one? Like a full breath half a breath or use the octo or what?

It's an Open Water Diver level question.
How many atmosphere's are you at?... and how much will that air expand upon ascent?
The fraction of air expansion will indicate how much air you need to put in the DSMB relative to its volume.
I guess the simple open water stuff was too much for ya???Now that's helpful. With that answer one can conclude that at 33' you would put in 3' worth.

At 2 atmosphere (33 foot) it will need to be 1/2 full to be full at the surface
At 3 atmosphere (66 foot) it will need to be 1/3 full to be full at the surface
At 4 atmosphere (99 foot) it will need to be 1/4 full to be full at the surface
At 5 atmosphere (132 foot) it will need to be 1/5 full to be full at the surface
etc. etc. etc.

No, I think I got it right. 3' worth in a 6' smb @ 33' sounds about right to me. Would you like me to explain the math to you?
