Just an observation here and providing food for thought. I'm going to avoid Beaslbob's Macroalgae thought, it's perfectly valid but incorporating it into my bacteria thought can quickly become confusing. For now let's just consider using only bacteria to process Ammonia into Nitrite and Nitrite into Nitrate.
Nitrifying bacteria are mostly only limited by surface area and food. Any reef tank with 1/2" or more of sand is going to have 10X more surface area than will ever be required to grow enough bacteria to process the ammonia from even an overstocked amount of livestock.
So, the limiting factor is usually food (Ammonia/Nitrite). When Ammonia is at 0.0ppm the bacteria present are consuming all available ammonia and there fore are limited by food. The population cannot rapidly increase because there is not enough food to feed a larger population.
If ammonia is reading 0.25ppm then the bacteria are free to reproduce, there is abundant ammonia to feed a growing population.
If ammonia is at 2.0ppm then the bacteria are free to reproduce, there is abundant ammonia to feed a growing population. They will not reproduce any faster than at the lower ammonia level of 0.25ppm. As long as ammonia does not register 0.0ppm they are not limited by food.
Don't know if you are addressing my comments or not, but yes I agree completely with your statements above. However the original thread was started to give options to the new aquarist. To help to decide on how much time and energy could be should be put into cycling a tank with live rock that may have much more life on it, than something like base rock or already cured rock that may or may not have the same amount of life. The option being of course to try to save as much life as possible by limiting the rise of ammonia to less than .5.
I think you know where I was going here Bang but just needed to make sure.
