Quick Pokertracker Hour question

[Jesse Kidd]

On Pokertracker, under Misc. Stats, you can see the hours played per month at various levels near the bottom of the screen, and the resulting bb/hr totals. How is this handled? If I am averaging 3.87 BB per hr on there, does that need to be divided by the number of tables I'm playing at once, or is this somehow already accounted for. I'm aware it's a dumb question, but I can't figure it out.
