The RTOW for that day with no wind was 185'070 kg.
The loadsheet TOW was 184'880 kg. This TOW was based on 2000 kg burn of taxi fuel.
1) Concorde on that day, according to BEA, burned 1000 kg on the taxiway. (800 Kg according to the F/E when challenged by the Captain as they line up on the runway)
2) 19 bags were missing on the loadsheet: an other 394 kg extra according to BEA
AF used the standard 84 kg weight for all pax, which was the most penalizing weight for that day. (Terrible safety culture...)
With these weight, and because of the bags error and the generous taxi fuel, Concorde was 1'181 kg overweight (0,6% of RTOW)
If you use the standard weight for male and female (88 and 70 kg) this will reduce the payload and the overweight was 687 kg. (0,35% of RTOW)
The wind at T/O time was 020/3 at the threshold 26 and 300/3 at the threshold 08. The tower mention 090/8 with the T/O clearance
I do believe that all these little errors were a contributing factors when you add them up.
AF or the arrogant French are not the only one in this world to play with taxi fuel to meet an RTOW or to make loadsheet errors on bags. My company, which is the second biggest British airline, is doing that everyday, (unintentionnaly of course)
