I like this...but not seeing the significance of 4226 as an inflection point. Maybe I am missing something, it won't be the first time.
Not sure I'd delegate it as an inflection point. Rather a measured 2nd leg down. PA likes to move in 2's. Nothing is perfect obviously - but you'd be amazed how often this happens essentially every day.
I expect lower levels than 4226 (3640-386) before its said and done though on other metrics.
