This is where having those preshot values come in handy on being able to advice on dose changes. Plus we aren't entirely sure those tests you are getting are his true nadir. Nadir isn't a fixed point in time. It is simply the lowest point in the cycle.
I realize that you have limited time to test but a full curve on a day off would be extremely helpful to get an idea on what the next step in dosing is. Is it possible in the near future you can run a curve? (testing every two hours)
