How recruitment picks an operator

The recruitment time sets the rarities a result can have: up to 3:50 gives 1★ to 4★, up to 7:30 gives 2★ to 5★, up to 9:00 gives 3★ to 5★. A 6-star only comes with the Top Operator tag; the pool holds 34 of them.

When the Top Operator tag is chosen and the recruitment time is set to 9 hours, a 6-star operator is guaranteed.

When the Senior Operator tag is chosen, the Top Operator tag is excluded, and the recruitment time is set to 9 hours, a 5-star operator is guaranteed.
