And so what's so weird about my collection???

Over the past few yesrs from time to time I would check out the Collection Matcher feature on this website. What I've never been able to figure out is why does the highest percentage of similar titles to my own collection BEGIN at 35 percent. I've browsed around and everyone here cross-pollinates at about 45-55 percent to begin with and, by the end of the list, declines down to the 35 percent at which I top out at.

At over 600 titles, I don't mathematically understand why my collection would be such an outlier in comparison to others. The chances in my collection showing up in in anyone elses Matcher list in next to nil. Not feeling creepy or "left out" about it. I just don't get it. Just figured I'd put my confusion to words here.

I don't consider my collection to be particularly niche-y or eclectic by any means so what am I not understanding here about how this works.
