First, since it's been a while since this was posted my DateTimeToday() obviously differ from the one on the result set, but that could be fixed with a filter before the comparison.
But another challenge was the start date. In the dataset the min date for datetime_finished is 2017-10-04 which I set to be the start date, but I could upon comparison see, that the seed start date was set to 2017-10-01, and once I did the same, the result matched.
