I found statement in an article "Good Practice in ( Pseudo ) Random Number Generation for Bioinformatics Applications" that you should not use too many random variables in a single simulation. Authors says that it maximum number of random values taken from PRNG should be $\frac{p}{1000}$ or even better $\frac{1}{200}\sqrt{p}$. $p$ is the period.
But I cannot see any references in other articles.
Do you know any reasons why not to use more values ?
