Nice. Keep logging for a few more weeks or even months
and tell us what happens, long-term.

I guess, yes, if the trend of the past *2* days continues
without change for the next *2500* days. But in the real
world what happens in a few days doesn't always match
what happens over a few weeks or years. If you continue
your data collection for the long-term it should make an
