One other thing...
The take-off run itself, from brake release until rotation can consume almost 500 kg. On a widebody. So if pure performance allows it ( performance calculations can be capped of by structural limits, but the pure performance is higher) , you will still be legal when rotating 😆...Not that I recommend this obviously..
Once again: the loadsheet is the legal documentation. That one HAS to be correct. The actual taxi routing etc. can vary.
