    I don't know, how bad Delphis random generator is, but I once years ago did make a mistake
of  calling randomize before random. It was a school assignment for using Turbo Pascal graphics.
So I made program, that was supposed to fill screen with random dots (colour was also set with 
random). Anyway, when I called randomize before random, then as a result dots didn't fill the 
screen, but were mostly along the diagonal of the screen. So I'd guess, that setting randseed 
multiple times could be actually bad for randomness of results. Or maybe modern algorithms are
better at situations like this?
