Manual spinnig is still needed when you want to create ultimate spun and readable articles. You must spin paragraphs and sentences if you want to create the ultimate spun article, it used to be a pain to spin huge articles in paragraph and sentence mode, the nested text always made it diffcult to find the right sentence. But now, with SpinnerChief 5's spin tree function, everything becomes clear and easy! All paragraphs and sentences are organized very well, you can locate, modify and spin them easily.
I've ranked websites in the past with spun content, and now they are still on #1 position of google. First year (2014) google found me because my spun was really bad, many paragraphs were just copied and my position drop from #2 to around #20 after a panda update. Later I cleaned all my text with better spun (I didn't buy any article!), my ranking went up again, and with more backlinks I reached #1 and it is still there
