@moollaza I went back and forth quite a few times on this particular sentence.

In previous feedback, there have been suggestions that my changes were breaking the conversational tone of the documentation.  So, in this case, I actually kept reading it aloud until it sounded natural and conversational to me.  I don't doubt that I have a bias toward the sound of colloquial American English, though. :grin:

I don't mind changing this, but I would prefer "vary around the world" to "vary across the world."
