Metabolix,
.. not doubting your reporting .. but the whole table might give us a clue as to what is going on .. the present tale sounds a tad strange to me.
MFS,
I can't recall any difference on the 733 for wind and nailing the target pitch was always a doddle .. especially if one did a raw data takeoff and didn't have that pesky FD getting in the way .. and I would be a bit concerned with the longer fuselages regarding the tailscrape problem using a lower Vr .. the story, though, just doesn't seem to add up ...
