Linday Head + Ralph Sewer

I just checked the West Torrens book and it has listed Head has playing 325 league and 11 cup games
does this mean the accepted total of 327 is wrong?
It also applies to goals (book has 518 + 16 cup)
I noticed the same for Ralph Sewer in the woodville book, If stated he played 325 games and kicked 403 (league + NS)
Are the accepted totals correct or the Woodville/West Torrens book.
As the book presents a breakdown its hard to argue with it
