For all of you that "slosh your carboy", if you are doing so with cap/lid on it, what are you really accomplishing? There is only so much O2 in that small amount of air so you are probably just waisting your time.
Your thinking suggests that all of the O2 from your bottle is staying in the wort. It isn't, only a small portion is. There is only so much O2 that can be absorbed, so exposing it to more doesn't mean that more will get in, only a better chance of infection. Nowhere near the amount O2 in the headspace would or could ever be absorbed into solution, so sloshing with the cap on, is just as effective, and much safer than slushing it around in an open bucket, or any other slosh method.
