I still think that "lifeless rock" does not specify how lifeless - theoretically extinct or just lifeless enough to make human life either extinct or just miserable. I took it as the latter, and in that case even lesser cases than 75% of all species would suffice.
The first case, the theoretical and non-human focused pov is quite another thing. Like you said, there's so many opportunities and adaptations for life to seap through the combs of doom :)
75% estimated extinction rate is quite close to me. :)
I've heard that Augustus wanted "his own month just like Julius" and that's how they took 2 days from february for july and august. That way we ended having less months with 30 days. Never did look it up if it's true.
I'm surprised they successfully attempted that and that it resulted to be taken positively. It seems as every out-of-the-norm scheduling idea is so frowned upon that even in small companies you can steer them to anything but the same ole.
I've used iso-weeks for this purpose. I don't really care for dates if I don't absolutely have to. It's nice to refer to "week 44 five years ago" in my journals. Truth be told, no one else around me uses the weeks and the only mention to it I've heard was not positive.
I feel offended - W%W-%w is my preferred way of noting down dates :D
Maybe this is a beginning of someone's mapping journey, so I wouldn't be too harsh on it. If you're interested in how the borders have changed throughout the history, you could also watch this https://www.youtube.com/watch?v=-6Wu0Q7x5D0
