The promotion board looks ahead 15 months, not just 6. The best indicator of the number of expected promotions is the number of 'A' grade candidates. With 180 'A' grades I would expect to see 60-80 promotions over the next 15 months. With a 6 month promotion prediction of 'nil' ACOS Manning clearly expect most or all of those promotions to happen in the second half of the promotion year, i.e., once manpower reviews, etc., are completed.
