Razor was very sharp this morning. Great shave! Think my main problem was avoiding slack in my strop, out of fear of rolling the razor's edge. Avoiding slack didn’t allow the edge to make sufficient contact to sharpen effectively. Regarding pressure, I had been using just the weight of the razor, which appears to work much better with a little slack in the strop. Hope I’ve passed the critical hurdle of being able to strop well enough to maintain a sharp blade. Stropping is such a critical part of straight razor shaving.
