Im far from experienced, but maybe he went low today..down from amps which was 232, then started rising up to the pmps? Its hard to tell tho when his nadir is from your test data, but seems around +5-6. I know you have health issues that keep you from testing, so you do what you can. hes on a low dose and wouldn't be surprised if he could possibly be going below 50 at some point, and you would take a reduction then. I guess the wise advisors would be able to shed some light, Im just guessing!
