comment FindFit returns worse result when putting constraints on parameters
@iwantmyphd Difficult to say without taking a look at the actual model and data. Why don't you post a question?

comment Long term growth model. Recurrence solution in NestList not behaving as expected compared to NDSolve
But I want to model how the system behaves under variable conditions doesn't justify abandoning the NDSolve strategy. What do you want to model? NDSolve[ ] is a pretty big monster

comment Solving for the limits of an integral
@ben18785 Because the integral behaves differently in different ranges. Try Plot[Integrate[ SquareWave[{2/10, 0}, ((x - 25/10)/10)], {x, a, 10 - a}], {a, -10,10}]
