Dear Method,

I see two problems with your calculating:
1) B2$01 is the year of birth of the last birth, not the first. The birth history is in reverse chronological order.
2) The calculation of age at first birth in v212 is made in months and years, not just years.

I don't know the term 'near' correct age. Can you explain where you find this?

BIDX is the index of the birth history and BORD is birth order. As you not BORD is in reverse order to BIDX, but with the first entry in the birth history being the most recent birth, not the first.
