Quick PT question about hours played
 

When I look under the Misc. Stats page the summary at the bottom shows the months Ive played and the hours each month. The Session Notes tab also shows hours played, except when I click on "show true hourly win rate" the hours played is alot lower. Is this because the Summary page shows how many table hours? Or is it something else Im missing. Sorry if this is a dumb question but I just noticed and am curious now. Thanks.
