I have come to appreciate the wisdom of the Virginia governor's term-limiting system -- you can hold office as many times as you want, but you cannot succeed yourself.
Voters can restore someone to office, but each term must stand alone, avoiding the, "What does every first-term President want? A second term." problem.
My approach: import unsharpened image from Darktable, scale down with NoHalo (added in GIMP 2.10, along with LoHalo), sharpen final image with unsharp mask. When downscaling a clean image, try 1-pixel radius, strength 0.35, threshold 0.05 as a starting point.
"None" interpolation is occasionally useful as well, in image with really striking edges.
Agreed that the older downscaling algorithms aren't great. My impression is that they do a nice mathematical job of downscaling, but not a great perceptual one.
The idea of indexing doesn't require a specific index. It is more general than that. The idea that average returns are pretty good, and average returns with low cost-of-management are even better.
In order to get average returns, the key is simply to own a tiny fraction of the entire market, whatever "market" means to you. The focus has long been on the S&P simply because it has historically done a pretty good job of representing the US equities market, it is market-cap weighted (unlike the Dow), and the earliest index funds tracked the S&P.
It's my expectation, stated without proof, that it should be easy to find a comparable index in Europe, if you want to match the average European return.
