Ah OK ! I can update the spreadsheet when the world border is expanded. Then it gives an idea of the type of chunk (1.7/1.8/1.9 etc.) an area exists out of.
I have mistaken this topic for a LVS one. What was the world border in LVS again? I'll make a second sheet for LVS. Probably no-one will use it, but I like making it.
