If a Security Measures run was completed, would the run use the in game time to calculate the final result or real time like on any other run? An example of IGT used would be a run done on the first floor. You have 3 minutes to complete the level, if one minute and ten seconds is shown on the timer at the end of the run, then the final time would be one minute and fifty seconds. Because of the detailed map, the requirement to kill every enemy on the floor, and the feature of the timer pausing whenever the menu comes up, pause buffering would likely be over used during the run. Whichever timing method is decided, real time would be most sensible for runs of the whole category and entire game runs.

the default timing of each zone is in real time.
