No idea how much time you had to play, but I doubt you did seven times the number of runs I did (which was maybe 260 or so, I stopped counting at some point) as I only found 1 PGF ... therefore you have to admit that while you surely did a lot of runs, you were extremely lucky to get that many PGFs. So you can have all the motivation you want, if the RNG doesn't like you there's nothing you can do about it ...
