Same here. I PM'd but should have replied publicly. Yes the results of this script are amazing and I just could not get my head around it either.
Performance is really bad (BUT IT WORKS)... I do need to tune it however and I am going to be working on that. The performance hit is in the joins. If anyone has a recommendation or modifications that would be great. Otherwise I will post what I come up with here.
