I think the main point is that you want higher resolution data, but
don't want to store individual results as they provide little data.
When we are trying to monitor certain things we want the results of
things like ping -c 30 every 30 seconds but definitely don't want to
store the results of individual echo responses. The problem with doing
things in PromQL with this type of data is that the resolution would
need to be superhigh to do meaningful comparison.

since last scrape, I would assume.

and by decide you mean any timeframe that is > scrape interval, right?
We are definitely giving this a spin. Thanks for the contribution,
this looks promising to solve a few issues for us:)
