I would not have thought the year 2025 would be the war of the prefixes.
You guys really need to understand this. You literally change 1 character and the prefix has no use. 1BY8GQbnuXX can be at the start of the range, while 1BY8GQbnuXXY can be at the very end of the range. There's no link. You can't reverse it. I'm having a hard time to even express this because it's such a stupid idea.
