When I did my check-in PRT (A-pool not API) the guys that run the PT program said that you needed a good low in your age/gender group to meet the API minimums. However NASC website says differently:
Males: PU=42, SU=50, Run= 12:00
Females: PU=17, SU=45, Run= 14:15
According to the website "These are absolute minimum requirements". Maybe someone who has classed up recently can say which is the standard they actually follow.
This swim test you speak of... consists of what?
After that Flight Management will do them randomly by last name (a-k's meet on the track) and that is every few weeks.
