Ben, I think the concept of pre-breathing has nearly nothing to do with activating your scrubber (except for temp around freezing temp), but more as a general test for your functioning rebreather: does it work or not!
meaning, cells, verifiing befhaviour of cells, is the scrubber working or do you feel weard when breathing (did you pack the scrubber correct, or at all) etc etc etc

I respect that it would check the cells and solonoid but i dont think it will show CO2 breakthrough in the short time, personal testing shows no signs until around 10 minutes with NO scrubber in the unit.
