This is a very good indicator, bro.
A couple of single views from "suggested" spread over the day / 48h can occur even on a "dead" (or shadowbanned/capped) channel, but once you see 2,3 or more of them coming in directly one after the other, it is a sign, that there is "something" happening in the background and that the algo is actually adjusting things (possibly refilling the threshold?)
That's exactly how my stats looked like right at the beginning of the last "viral phase" on my channel. It all started with 2-3 views per hour from "suggested" (they came out of a sudden). Views from "suggested" kept growing and cumulating hour by hour, day by day and after a week, you know, BOOM! - views were exploding (channelwide).
It's like a steam train starting slow, but accelerating more and more.
