Narrative:
Before push back we received our final weights and then pushed back for departure as per SOP. While taxiing to the runway; we received no less than four final weight adjustments. This was a distraction in attempting to sort out the actual weight and performance of the aircraft while attempting to accomplish pre departure duties. The last zero fuel weight (ZFW) was 134.0. We were then cleared for takeoff and were satisfied with the weight and performance of the aircraft. The takeoff roll seemed a little long and the rotation was achieved with about 2; 500 feet left on a 10;500 foot runway.seven minutes after departure we received another update on our final weights. The weight increase was 3;500 lbs. To ZFW of 137.5. We did the performance for a ZFW of 134.0 not 137.0. I believe the problem with this is obvious.
