The only thing I have noticed though, is that the number of readers goes down between the first part and the last part - usually almost by half - when stories are split into parts or serialized. Unless this information is not being captured correctly, I think it means that it may not be overly advantageous to split stories, at least in terms of readership.
I think you're mis-interpreting the data. Simply because a reader views a longer story (or even a shorter) doesn't mean that he/she has read the whole thing. For many reasons, a reader who starts reading a story may not finish. The reader may not think the story is well-written, or may not like the genre, may not favor the orientation (remember that a number of views will occur before the story has even been validated), or (for a longer story) may not have time to finish it at first and then just not get back to it or may find it simply doesn't hold his/her interest. A one-part story started by a reader still is shown as "viewed" but that doesn't mean it has been read in its entirety. With a serial or multi-part story, you just have concrete evidence that the reader didn't finish. You may scare away a reader with a monolithic 15,000-word story, but whether it it's posted as one or in parts, once people start reading you will lose some of them along the way in eitehr case. I've never posted a multi-part story, but I don't try to fool myself into believing that every 'view' represents a complete read.
