All you have to do is save the game at the point you which to measure performance.

Hit "Continue" and load up the game each time. Don't move, just take down the numbers. It is a very repeatable procedure, with no variables to account for unless a Splicer happens to walk on screen, which is unlikely. If that happened though, the test would be repeated.
