Okay I think I figured part of it out (THINK). We'll see, check this out: 
my $result_row = $id - 1;

My assumption that the row numbers were out of sync was incorrect. Apparently both the result rows, and the HTTP response ID start with row "1". So I was fetching stuff that was out of sync. Now the records match up. Strange thing is though that even though I just submitted 100 requests, it returned 233 with html_content that wasn't associated with an ID or anything.
