Do you still have your original code? Finding out if the weird repeats were real, and especially why, would make a super interesting blog post.

The old code was var r = new Random() ;)

I'm assuming I either hit an PRNG bug (after all, I encountered a compiler bug in university already), or more likely, that I simply imagined the issue or bad bad luck with the data. Never did a statistical analysis after all.
