Initially, I wanted to write 18cm..., but I remembered that censorship is prohibited, so I added 20cm later, referring to a ruler) (because 18cm rulers don't exist unless you break them, of course)
P.S. Okay, maybe I can't count? You're much smarter than me, and maybe you know such numbers as 16 and 17) ... in any case, they can be added there, like in the case of the numbers 11, 12, 13)
But even this doesn't change anything, because in all forum games, there are off-topic posts or incorrect ones (in the forums, posts are repeated or just nonsense is written, as in many questions or answers), so why aren't you lowering the rating there?
And this rating decrease of yours is just another nitpick.
