It's quite good, have found a few already today in that time zone between 1903 and 1927!!
Marriages from about 1905 onwards are matched up with spouses's in some case's..
But I did come across quite a lot of records of just names with no year of birth too, and I've searched for a birth that I know is on familysearch but it's not coming up....
Hopefully in time it will settle down but the recent, births, deaths and marriages will help quite a lot!
