I understand your point, but there are other factors that come into play. I have seen auto shooters that will fire 3-5 shots on each target as fast as they can knowing that they have the rounds to spare. Revolver shooters CAN shoot as fast, but are generally more deliberate with the shots they fire. If I shoot at the pace of an auto shooter that has a high volume of shots, I'll not be putting my shots where they should go as well. Now If I shoot at my pace I can put my two shots where they need to go in the same time that the auto shooter empties the 3-5 shots they fire. This would mean that my tempo is slower than the auto shooter, but I am getting the shots where they need to be in about the same time overall.
Watching some of the videos of some of the higher level auto and revolver shooters shooting the same stages, there is a clear difference in the tempo they have. There times are close, but the auto edges out the revolver the majority of the time strictly on tempo. Yes the reloading makes a difference, but I have seen Miculek reload as fast or faster than many auto shooters. Even then competitors that are of the same caliber as miculek often edge him out on stages using autos.
Its the difference between trying to get the shots off as fast as you can, and trying to get the shots off where you want them as fast as you can. No offense meant to anyone, as it is all a game.
