I addressed all of this in depth at the time (ironically, in a submission of the same URL that you posted, which wasn't killed):

That took hours, and I don't have hours to write anything new. If, after reading those comments, you still think there's something I haven't addressed, please double-check to make double-sure that I didn't address it. If it passes that test, ask me then and I'll try to answer. In the meantime, though, please don't post new variations in this endless sequence.
