SS looks good now! I would probably make just one change at a time so you can see if it is helping or not. So maybe try the schedule change if that is easiest. Or if you can get a nightime test or two in to check for a nadir, if that is not in non-diabetic numbers you could do a 0.2 nighttime increase, but maybe keep the timing the same for now. I think if you change both at once and the #s aren't perfect, it may be more confusing than anything else...?
