Y’all forgot to the account that the water absorbs some of the smoke and all the things that are in it. I have smoked for 20 years I have smoked through everything and anything, and all forms from flower to hash dabs edibles and everything in between. I would say with a normal bong and a normal hit 1 bong hit= 3 hits off of any thing else( joint, blunt, pipe etc.) Just keep in mind the the thc% substance is the same in the way your smoking it. There is some real life info for you peeps.
