You can't verify it, but why should I make it up?
The fact that I agree that most models exaggerate their reaction and that I almost never watch professional videos because I have no guarantee that they are genuine should be a good clue that I'm not biased or trying to delude myself.
Moreover I don't like girls who are too ticklish and start to scream immediately, my personal preference are by far girls who are able to hold back at the start and you have to work hard to crack them.
I like a "challenge" so to speak, and I'm dissapointed that the vast majority of girls I tickled laughed very easily, so I'm not biased in that sense either.
I'm just discussing the matter objectively based on my personal experience.
I have watched like 4 or 5 one-hour long canelli videos, so I don't which one you are referring to.
Unfortunately I can't check them anymore since Pornhub took them down with the recent purge....
By the way, speaking of Canelli videos, I'm going to post some videos of girls with different degrees of ticklishness to see how you would rate their ticklishness and what do you consider "ticklish" or "worth being tickled" and if it matches with my standards, let me know what you think about them:

In my book every single one of them is ticklish and absolutely "worth being tickled", despite the very big individual difference in their ticklishness level.
P.S: Do you understand Italian? Because I do, and maybe that's why some renfaire girls may seem less ticklish to you than me.
In some clips I remember watching there were girls who were not laughing out loud that much, but they were still verbally expressing a lot of distress and costantly begging the ticklers to stop.
