strangely enough, the time doesn't concern me. what concerns me is the fact that you completed it with only 4 portals, which leads me to believe you exploited a glitch.
breaking this record will require careful research and thorough study.
edit: after some careful research and thorough study, I have found a method that is sure to destroy your record. however, this method requires much practice, and after several hours of said practice, I have nearly perfected it. please standby for record destruction.
