Also any evidence that the -1000 has been able to benefit from any deviations be they positive or negative. Seems little being said on both airframe or powerplants.
The -1000 got a wing twist tweak that will be backported to the 900 (IMU).
My understanding is that the overweight "Batch 1/2" frames did not encroach on performance guarantees.
Performance data and airframe reserves seem to have lead to the ULR being a direct -900 derivative
instead of a shrink -1000.
Nothing available for leveraging media rah rah on performance shortfalls.
U-Turn AlBaker has to resort to renege on minor carpeting issues.
My guess: the A350 is well above projected data but nobody feels about writing that up.
