Enrollment is one of a number of limiting factors that can affect overall performance, but it is only one of a number of variables. The trick to a limiting factor is that just because less of something can limit your chances, having more doesn't necessarily help in proportion.
To quote Papa John, "The best pizzas start with the best ingredients." While this is true, just having the best ingredients on hand certainly doesn't guarantee that you have the recipe and the skill to produce the best pizza with them.
Since it's the beginning of grilling season, I'll continue the food metaphor...just having the best cut of meat doesn't necessarily mean you can grill the best steak...but it sure helps. Still, it's a lot easier to take a great cut of meat and make it tough than it is to take a tough cut of meat and make it tender. Top-quality ingredients are a lot more forgiving of error, but there are still many more variables that can keep them from transforming into a top-quality dish.
Make sense?
