=========== AdaptiveETA

AdaptiveETA estimates time remaining from the last few seconds.

Reach for it when the processing rate can change mid-run (resuming a paused job, or one that starts slow and speeds up) so the estimate should track the current pace rather than the whole-run average that plain ETA uses. The window size comes from SamplesMixin's samples argument: an update count or a time span. In the demo, the run starts slow and speeds up partway through, and the countdown visibly drops as the estimate catches on.
