Driving the same bit of road with a gradient over and over is a good test to see if the latest tweak or correction has made any difference, or if there has been an undiagnosed fall-off in power? There is a length of old lane near me, with trees along to shelter it from the wind, and if the car will climb that comfortably in top at just over 30, then it is about where it has always been. If I have to change down, then something is not right, given I am not two (or more) up at the time.
