So long as the actual temperature and pressure didn't deviate by a certain tolerance from the paper numbers the plane was good to go.
What I found more concerning was the tiny margin on some of those calculations. Some calculations had less than 100m runway remaining. That's not much room for error.
I routinely see stop margins of 1m. Provided the difference between flex and actual temps is high it's not a problem.
