The NEST and Hardships work on a slight delay. If an NCEPT panel is on the 14th, it's all about when their list is generated. Lists could be (hypothetically) generated using data on the 13th, then you have time for each to rank, turn in, select, etc. In terms of showing up on the PPT, they were all accounted for between 3/22 and the next update on 4/25.
The Academy placement is the only list that draws from the staffing workbook data with a little more frequency, but as you're seen in the past, that's not without it's faults either. Although it's more common in Enroute, you'd have instances like so....
1 - Reserved for Academy Grad
2 - Reserved for Academy Grad
NCEPT panel happens, they select 8 people, those spots are designated as 3 - 10. If the second academy slot is not selected (or enough people fail that it ends up not being offered). Those 8 people with designated spots 3-10 don't more to 2-9, the 2nd academy slot stays atop the enroute placement list for the next academy class.
