Right or wrong, I worry that negative packing is the best way in the world to tear your lungs loose from the pleural cavity, so I keep well away from it.
The variability is beyond me. I know some days I never get past 60 seconds, and on a few I do multiple 120s. Since I can't figure me out, I have no clue about anyone else. ; )

although i know they feel excruciating, i don't think this kind of self-inflicted damage is possible (at least under normal conditions).
in order to train empty lungs and diaphragm stretching and control certain yoga postures can be very helpful. one is called
uddiyana bahdha, which is an abdominal lock. do some research and reading before rushing into it and allow lots of time for your body to adapt before pushing (don't just copy the video below).
self-inflicted barotrauma is unlikely at normal ambient air pressure; however, it is more than likely when combined with the added pressure caused by increasing depth, especially without appropriate time for adaptation. negatives done in the water can and do cause lung injury if not approached cautiously.
howard, the variable negative breath hold times you describe are likely caused by starting with differing amounts of air (assuming other more obvious factors were held consistent, such as time elapsed since last eating).
as an example, here someone doing uddiyana bandha and
nauli kriya
cheers and enjoy freaking people out with your developing vacuum belly technique,
