No offense ryan, but i hardly believe that was legit. Bryans run was about as good as it gets up till the end, and he blew the glass. he exited a second or two later than he COULD have, but still overall it was very good. 4:13 seems easy if you leave in 14 seconds =p.
And Illu is right, natalya leaves faster if youre further away, i already told henrik that though. Maybe a guard is in the way or something. are you shooting at the desk till it is 100% gone? i mean all the blackened parts are gone too? maybe try throwing a mine on the lift door a few seconds before she completes to clear out any guard that might be standing around. also try not to even look at her as you exit, like dont even look toward her at all? you know how bryan goes down that stairway? do that but dont look at her. Id say keep exiting in 18-19 seconds, i mean she should complete once, or thats what they say anyway.
