Most prop speed controls will try and maintain prop RPM which at lower speeds may be course enough to stall the prop just keeping it from over-rev. Manual 100% RPM will waste full power but at least be a bit better than prop AOA too high. Either way is "spinning wheels" without smoke and noise to show it.
Getting the most out of a plane isn't 'simply' anything.
If you want accurate data, get a devicelink data logger like UDPSpeed and ditch the stopwatch.

I'm trying to do this from the general player population's point of view; I expect that anyone using the same methods would be able to get very close to the same results that I do, which is the whole point. I don't use a stopwatch, just the track's time displayed in the lower right hand corner. The tool I use most by far is the 'Pause' key.
As for prop speed, for most cases I use the 100% prop pitch setting because it is loosely analogous to low gear in a car; unfortunately, when I try to get a fast start from first gear in a car, I can gauge how much power to apply by feel, something that is not available to the virtual pilot, so I felt that I had to keep things fairly basic. I tried a few experiments with the Spit IX and the P-51C with the engines at both 2700 and 3000 rpm, which are included in the Spitfirepalooza and USAAF fighters charts. The Spit at 3000rpm is superior to the Spit at 2700 at all speeds, while the Mustang at 3000 will rip past the Mustang at 2800 until they reach about 510 kph indicated, at which point the Pony flying at 2700 rpm passed and reached 530 IAS almost a minute sooner (looking at the data table, the 2700rpm bird actually seems to start gaining speed faster around the 490 kph point, which is where I would suggest 'changing gears' if you have to run away from trouble). The Spit IX and the P-51 have very similar if not exactly the same engines, so I figured it would be a good comparison to work with. I created a special chart demonstrating the differences which I will attach below.
I left the Germans' prop pitch, with their 'automatic transmissions', alone, but most of the other aircraft seemed to respond better to just pushing the prop pitch all the way forward at the same time you shove the throttle to the stops. In all cases, I make sure that the supercharger is in the right stage, the mixture setting is appropriate (for instance, the Soviet fighters all ran better at 80% mixture at 3050m than at 100%, while the CW-21B needed 120% mixture to keep even with the Zeke 21) and that the aircraft is trimmed for level flight at 270 kph IAS at around the suggested rpm for cruise (and that the engine is relatively cool).
If someone expert in one type or another feels that he can obtain better results with different settings in a given type, I invite them to put their oar in and help out the community at large.
