Perfect aircraft load penalty?!

[PH-MD11]

Pilot's Penalty points: -450 points
You exceeded the maximum take-off weight of your aircraft by 0 lbs and this is very dangerous. (-450)

You may have been 100.1% of your payload. Or just half a pound over something silly like that, I doubt if FSP differentiates so to be
careful I've always maxed out at 99% load.
