Sorry, I would've posted yesterday, but I can't view SS's well on my phone.
It's hard for me to tell what's going on, because you keep changing your dose. Cass does best if I hold a dose for a week or more before making changes (except for really obvious ones, like going too low). I don't really have much experience with shooting on a sliding scale. It does look like the numbers are better with lower doses. You may want to try picking a dose, like .75u and hold for at least 3 days (not cycles, DAYS) and see if you notice a pattern.
