    Has compression recently improved a lot more?

    I have plotted the following graph of the best compressors on Matt's site:-

    I was unable to incorporate dates into the x axis, so it's not to scale. But by inspection, there seems to be a downwards kink at the right hand side. Is this simply bad graph work on my part, or has anyone noticed an increase in the incremental improvement between recent algorithms?

    Yes. Practical compression has improved with Woff 2.0 (unknown to people here, but its launch was the only internet payload size drop ever recorded on, brotli and zstd. Super light byte-based compression has been sped up during recent years. Media compression benefits from simd and multi-core. Alex won another Hutter prize last year. Neural compression research is emerging. Traditional impractically slow research compression has made a lot of progress.
