I'm a little confused by a flight I have coming up to PVG (BA169). The BA seat map both out and in-bound is showing row 16 as club. The forum dashboard sticky and seat guru show row 15 as the last one in club. Has the format changed?

Also there is no 21 A/B and J/K (although 21DEFG are all there). Does this mean 22 A/B and J/K have more leg room?
