A visit to a topic. Duplicate visits from the same user are counted after a 8 hour interval. A user is either a logged in user or an IP address for anonymous visitors. The 8 hour interval can be changed with the site setting topic view duration hours.

so you could set topic view duration hours to 1 for instance.
