If you are restricting the outputs to integers, then the process is NOT
normal. It is at best approximately normal. Perhaps you could better
model it with a suitable discrete distribution (binomial? Poisson?) and
match the moments?
If, for example, a binomial model with parameters n and p works well
then a normal approximation will work tolerably well if both np and
n(1-p) are greater than 10, i.e., modest n for p near 0.5 and increasing
requirements for n as p gets closer to zero or one.
