summarizeWindow(Duration windowSize)
Summarises the history of values in this time window, with a few special things:
If entire time-window is not covered by the given values, then min is Integer.MIN_VALUE and max is Integer.MAX_VALUE
If no values, then latest is -1
If no recent values, then keeps last-seen value (no matter how old), to use that
"stable for growth" means that since that max value, there have not been any higher values
"stable for shrinking" means that since that low value, there have not been any lower values
