This is like the 100 year or 500 year flood. What that means in the real world is that in any given year, you can have a flood 1% or 0.5% of the time. So yes, Virginia, you can get back to back 100 year floods, even in the same year.
Plus, the reports of good and bad streaks do help confirm that the pRNG is working correctly. Systematically kept records, over many trials, will help constrain the success (or failure) rates and help you spot anomalies properly. The reports, by themselves, don't tell you anything else other than that particular person's perception or memory of a particular result (typically one that stands out because it is negative).

On planet Earth, there is a try.
Indeed, in a world and life full of change, the only constant is human nature (A is A, after all :P).
