Good work today. Well, today at least his nadir (lowest point) was at +8 which is a little longer duration than we might expect. But your numbers in general, while good and not dangerously high, could go down some.
If you are not going to get a pmps, I would stay with one unit tonight. Tomorrow, barring something unexpected like a lower than normal amps, I would think you could increase to 1.25. And then get in a nadir check around 6-8 hours after the shot.
Great job today to all three of you.
