AFAIK lithium isn’t used for long duration storage
Right now that's true, but it's a price limitation, not a technical limitation.

Oh yeah, great one. I love knots. When I don’t have a technical puzzle to mull over while drifting off to sleep I like to visualise knots - it’s surprisingly tricky to follow along without a line in your hand.
Everyone should learn the bowline because it gives you a lot of bang for buck. One I discovered on the brilliant website below that I’ve really come to love is the tumble hitch (quick release hitch on a bight).
Thanks for the links, that's a cool site!

It seems like median would be a much better metric than mean here.

What a weird way to visualize this data. A simple histogram or CDF plot would have shown the patterns quite well. This way it's hard to follow the bands and blobs, which seem to be based on completely arbitrary cutoffs. It doesn't even seem to follow its own strange logic, jumping suddenly from just under $100K (1% per blob) to over $100K (8%) in a different part of the diagram. Why would anyone do this?
I totally agree, it's not a very clear way to show the data.
