Dave R - thanks.
Vref at MLW is 118kts (I haven't done any DA adjustments) although I suspect Vref in this particular scenario would be nearer to 110kts.
athonite - 1059m is easily enough if you fly using book figures. Adding the industry standard AOC/public transport safety factor of 0.6 only just puts you out of spec (not that I'm condoning such action).
littco, I'm not assuming it "landed on the numbers", I'm assuming it (should have) crossed the numbers at 50ft at Vref. You may as well throw the whole book away if you don't fly by the prescribed performance criteria and bung on 30kts.
PS. The figures I've used do assume a serviceable aircraft.
