That’s right:
There’s only one thing in each room to find, with 4 specific starting points that are not random:
So:
room 1: find 1 target 4 times, each time from a different location in the room, then
Room 2: find 1 target again 4 times, again each time from a different location.
Finally:
A) Return to room 1 and in a completely different position to previous times to find the same room 1 target once.
B) Return to room 2 and in a different position to previous attempts in this room to find the same room 2 target once.
End game.
