as I have come to understand the way eink screens work, a page turn is actually two actions. the first clears the current image on the screen and the second shows the new content. so, maybe the question is how do the makers define a page turn? maybe a lot of them are counting each action when providing the quoted number. so, 8000 page turns is really 4000 actual page viewings. this would seem more consistent with the numbers people seem to be reporting here and other places i fine while deciding what reader to buy.
