If the videos didn't manage to explain then I've got nothing more. Except a bunch of words:
I don't have a force gauge so I'm not going to be able to prove numerically that I was pressing far less on the Shindo than the Shinkiro, but you can use the sound of the blade hitting the board as a proxy. Louder means there was more force left over after cutting through the carrot. Cracking distance is basically the same measurement really, since horizontal velocity is basically waste (though arguably assists in food release, which I don't prioritize that heavily).
And assuming the carrot is the same density, which I think we can since they were halves of the same carrot, that means both are measurements of how much extra force was applied to cut the carrot over the minimum. A hypothetical perfect blade wielded by a perfect user that "ghosts" through would cause no sound hitting the board.
I think most real blades will crack a sufficiently large carrot to some extent, since you'd need an essentially infinitely thin blade not to do so, but I think it's still a question of amounts. The more it cracks, the less clean slices you're getting and the more force you're having to exert.
Ultimately, I think this is a question of preferences. Most of my cutting ends up being hard vegetables, so if the knife isn't good at that then I just won't use it. Also, lots of people on this forum lean towards (IMO) ridiculously thick, long and heavy knives. I don't really have much interest in those.
