There is nothing strange about this. Randomize initialises randseed
based on the system clock value expressed in seconds. So if you run
it twice in the same second, you will get the same number.
You are not generating a series of random numbers based on the
Mersenne Twister here, because you only
Hi,
I am not a mathematician myself, but I predict that unless you make
extensive tests over a very long period of time you will never find any
corelations!

And then you have to compare the random numbers generated in one

And note that even then you may get two times the same number after
each other. There is nothing wrong with that though, since if tha
