Something I've noticed with the System Stats plugin. (don't know if bug or by design)
When you browse to the Stats tab (or Settings item), you see real-time data that slowly populates, until the [sliding window time] is reached, in which case the sliding starts.
What I expected to see was data for [sliding window time] that updates in real-time off the bat. i.e. data a window that is full of data, and has already begun sliding.
This data exists, because if you switch to anything other than real-time, you can see it.
As-is, the only way to see data of something that just happened without having Stats open in another tab is to switch to Last Day for sliding window, and this isn't very granular at all.
Unless I'm completely missing something here.
