I made a note of some of the sets I keyed on September 7th last year. This was when the Liverpool Crew Lists project page was updated with the images showing a correctly keyed Crew List and a Ship Information page with the required date highlighted, as I was curious to see if it would make any difference to the errors which keep cropping up in review.
Some of these set numbers were 2234045_1470, 2234106_59, and 2234110_17.
This morning I downloaded a batch to review, which contains set numbers 2234045_1447, and 2234106_70.
So the reviewing is about 7 months behind the keying!
