I'm not sure if the MAC noted 29% in the note is not a typo for "around 39%". When looking at the "target CG" as it should be computed by the fuel-computer (FCMC) for a 205 tonnes ground weight aircraft, it will give a MAC around 37.75% (target). Hence, it should vary in this part of the flight between 37.25% and 37.75% (while maximum certified AFT should be above 39.75% with a 2% safe margin).
