I wish there was a record of how the speed and memory requirements changed over time.

If you look at the 10 year history of the challenge, most entries were small gains, but over time all this adds up to a significant improvement.

Tom, you are correct that it doesn’t matters to normal users “yet”, but almost all technology the normal users are using today (or will use in future) is a result of such state-of-the-art work by researchers.

Does this 0.5% improvement matters to anyone?

You researchers must be excited about this, but all this effort is a useless overkill.

And PAQ is sooooooo slow…
