Narutoforums doesn't even have the translated page for that anymore, I already checked. BUT when they did, I remember the translations saying the same thing.

edit

The Databooks follow the same principle on all of its character info.. weight, height, stats, age, all of those are from the last chapter of the last volume it covers. In the stat section, it covers the LAST battle they had. Hence Naruto still being the same size and age at the end of DB4 because an entire year has not passed and the DB4 only covers up to October 9th. It also explains why Naruto only had a 26 total in stats at the end of DB3, because he didn't even start Rasenshuriken training yet.
