I still suspect this is bounce resonance. I suspect he dropped low that night of the nasty red but I can't prove it. We will see where he goes tonite and I guess increase again tomorrow.
The reason I track some bounces closer than you might expect is to potentially "steer" a sharp drop to a softer landing and perhaps lessen the next bounce. Of course I also attempt to "defuse" highs with a bolus... something of course only for those with plenty of experience and data.
Just got to keep at it until he gets re-accustomed to normal numbers.
Hey............Davidson said it's about time and Harley just gave me a dumb look when I read them the posts...............Harley doesn't get it, but that's okay - we do! Hopefully you get a few more greens!
