Hi Greg, I'm not a 757 pilot so I can't give those figures, but have you had a look at something like one of the flight sim add-on packages available. There aren't many 757 ones around, but I'd highly recommend level d's 767, almost same cockpit etc, and easy to find any useful information for your class... It is (so I'm told) quite accurate in performance and many of the charts/tables are available through these programmes.
