It's a script that toggles back on the DVR feature on livestream which means you can go back to earlier points of the stream. Most streamers/Holos turn this off for whatever reasons.
.66 to 4 seconds is fine and normal. The stream is uploaded to you in chunks like that so the stream can cope with minor hiccups. If you check out Aqua's streams they're usually delayed by like 20 seconds which you can also catch up by doing the x2 speed trick. The small delay is dependent on settings the streamers use. Just to clarify, this won't get you past actual stream delays they might add on their end.
