Well, as to number of generations, I’m really trying to figure this out for real, not just say something’s true and forget about it.
Human and primate reproduction would require us to take the number of years and divide by 10 or 15. For small mammals, perhaps one generation per year.
I’ve looked at the “evolution time line” that is generally accepted and there is no possible way that enough evolution could have occurred. I actually researched a bit, and found that the actual evolution “scientists” are also unable to support their own theory, very much to my surprise. They simply refer to the “Cambrian explosion” as a possible time period of extremely fast evolution, and beyond that they simply say that evolution must be true, so therefore it is.
As far as the theory of gravity, the force of gravitation local to our environment on earth is observable when one drops an object, so the existence of gravity is without doubt; objects can’t hover without energy. The theories regarding gravitation have to do with mathematically defining the force to reflect a complete understanding of it, and so far there is no theory that satisfactorily describes gravity, general relativity and quantum mechanics in a unified way. Newton’s law of universal gravitation, however, which describes the simple observable gravity above, is called a law because it can be proved through observation.
Your last paragraph, “We know evolution to be fact”... etc., demonstrates the logical fallacy of “begging the question”, the most basic fallacy that all scientific endeavor must overcome in order to rise above conjecture in a bar.
I know, I was not mocking you. It would be impossible to estimate, since the arrival of the first mammals happened somewhere between 190 and 140 millions years ago.
That gives you a 50 millions year spread, so it would reasonably throw your calculations off in the millions, even if you divided by 15 for humans, which wouldn't be accurate either since they didn't even show up until tens of millions of years after that.
I don't think its something that's knowable.

I don't understand how you could possibly calculate this. What defines "enough evolution"? You couldn't even get evolutionary biologists to postulate something like that. In some cases they're still fighting over the concept of punctuated equilibrium.
Evolution occurred. We can see it in the fossil record and in transitional fossils. To paraphrase Haldane, we haven't found rabbits in the Precambrian yet.
Newton didn't know the nature of gravity, and it took theories to postulate its nature.
As Einstein proved, it wasn't really a force at all, but a warping of spacetime. Maybe someone will come along and be able to usurp the current theory of evolution and explain how life evolved, but it doesn't change the fact that evolution occurs, even right before our eyes with fruit flies and bacteria, and with the fossil record in specimens like the platypus jaw to archaeopteryx.
Whether its a slow process, punctuated equilibrium, or a combination of both is for future scientists to discover.
If you come up with a better theory, the world will beat a path to your door, not to mention fame and fortune.
