John I suspect your right and I never questioned Hudsons or anyone elses qualifications, however I think the question was Vspeeds to use for takeoff BRW of 55T if your perf limired TOW was 65T, and I still stick by Vspeeds for 55T not 65T.
As you said you have a range of Vspeeds for a weight, If you want a higher V1 why not just get jep or your own perf dept to run max V1 as an option for 55T, if thats you aim, or min V1 if thats your other aim?
Either way I wasnt suggesting u wouldnt get away with using those higher speeds associated with an artificialy higher weight, just that technicly I believe it incorrect unless the analyses has been done.
If ive still missed the point then bollocks to it.
