General Question Concerning No Show Pilots

[Bluemax]

Recently we had a recruiting drive that netted us 22 new members, of them 8, never got out of the gate [Never made a flight] so after 72 hours if they fail to report for duty, we drop them from the roster. Now I can understand taking a hit at VA Central for deleting inactive members who have contributed to the program and just moved on. But we lost two slots for deleting pilots who never contributed a single flight? I thought I understood the formula but this has me puzzled. If we want to maintain our ranking, does this mean you never delete pilots whether they have contributed or not?
