Your views are tabulated initially. Sometime later, possibly intra-day, they are adjusted to reflect real views that don't originate from your computer. If you have been giving 10 hubs a second look, your view count will rise by 10, and this may even appear as rising traffic on individual hubs that you refresh; later on, you'll find that you have less views, because your views have been taken out. If you review your hubs a lot a particular day, this will manifest as surging views, and eventually the more realistic and accurate view count will emerge. A note of caution: Some of these views have a way of never being offset, and you can check, say, in the analytics breakdown of visitors by geographic region that your city is disproportionately represented.
