This works in theory, but if your program has been running for a minute, going back a second by re-executing from the beginning will take a minute. rr snapshots every second so that going back takes similar time to going forward, rounded to seconds, adjusted for overhead.

True — modulo speed ups from materializing ND values from the log itself.
