You're not the only one hung up on it, no. But I don't see anything strange about a 10/10 score. It doesn't imply perfection, only relative excellence.

This is how it's always been with game reviews, for instance. A video game released in 1996 gets a 10/10 because it's better than other games yet seen. The same game released today would get panned. It doesn't imply any claim to absolute perfection.
