The number of views counted includes all the times that you view it in edit mode.
Each time you click "save" it counts as a view. There is also an auto save facility (I'm not quite sure how often but every few minutes or so) that has the same effect of adding to your view count.
I find that by the time I have a hub "done and dusted" and ready to be published, I have around 20 views already on the clock.
For earning purposes your own views like these are discounted, so don't worry about them.
