That is not what that article says or implies. I think that you may have a reading comprehension problem due to your prejudice. It compares two different means of stunning. One of them had unconsciousness in all examples. That was the bulls that were stunned with a penetrating bolt. For the ones stunned with a nonpenetrating bolt there was a record of 82% being completely unconscious:The pattern of changes in EEG activity following captive bolt stunning, between and within captive bolt gun treatments groups, was not uniform (Fig. 1, Fig. 2). For all animals, there were periods of movement artefact in the EEG immediately after shooting. The duration of the initial period of movement artefact varied between the treatments, with cattle shot with the PCB having a mean initial duration of 2.3 ± 0.2 (range 1–5) seconds and NPCB 1.6 ± 0.4 (range 1–4) seconds, however the difference was not significant (p = .117). For both treatment groups, in most animals movement artefact was followed by transitional EEG, with further bursts of movement artefact and transitional EEG before changing into isoelectric waveforms.The EEG waveforms of successfully stunned bulls generally followed a pattern of transitional or HALF activity before becoming isoelectric.Electroencephalographic assessment of pneumatically powered penetrating and non-penetrating captive-bolt stunning of bulls

*shakes my head* Dude. They are suffering during the stunning. Details, details are important. Saying they're stunned ignores how they got that way. And if you *actually* read the research I just posted you'll see, this is not an error-free process. Yes, sometimes it takes 2 bolts. Sometimes, it simply doesn't work and they do for it.
It's better to leave this kind of work to a pro with a long sharp knife.
"s. After stunning two NPCB bulls had periods of normal EEG activity and maintenance (Ptot, delta, theta, beta) or increased (alpha) spectral power compared to pre-treatment values, indicating incomplete concussion. The study showed that pneumatic PCB stunning was effective in rendering all bulls unconscious, while NPCB was less effective. This highlights the potential animal welfare risks associated with NPCB compared to PCB stunning of mature bulls in commercial abattoirs."
They are obviously recommending that NPCB not be used and instead just a penetrating bolt concussion device should be used. And when it comes to a "pro with a long knife" that is never instantaneous. Even with an incomplete stun an animal may be in less pain than when its throat is cut. We have not even tried to compare those two at all.
In other words, your source only showed what sort of stunning that should not be used. It did not make a case for your system at all.
