Well, I am thinking the 160 this am has to reflect either a low nadir overnight or a long cycle. So I am thinking the other parts of his cycle today are a reaction to a low. This seems to be his pattern. In reaction to a low number, the next day is high and flat or even a little inverse.
He is bouncing around a lot and that means some pinks in reaction to the blues and greens. But generally he is giving you some good numbers. They are just not consistent, therefore frustrating.
I would just stay the course, enjoy him, keep shooting and collecting data. It will work out, just not on our desired timeline. :dizcat
