When searching repos in bitbucket I notice the "All Time" follower count is way off. For example, If I search on "python koans", my repo "gregmalcolm/python_koans" is listed as having 138 followers. But follow the link to the actual repo and you'll see I only have 82.
Also I think the "Month" filter is broken too. it lists me as having 52 followers this month. I'm not sure what the exact figure is, but I think its closer to 25.
