I have very different experience with YVR-PVG AC25/26. Was 100% (4 out of 4) success during my two years as E. As an SE this year, it was 100% (5 out of 5) so far, and it looks like an excellent shot for my 6th upgrade on 5/21 back to YVR. All from T+ fare. [update: got my 6th upgrade on AC26 5/21 - cleared at T-2]
Yes 763s have fewer J seats, but the YVR-PVG city pair is a smaller market. Percentage wise a 763 has same % of seats in J (relative to total # of seats) as a 77W.
