However you could say that if no extra unnecessary checking takes place then the total number of actuations = (days flown*3) + (flights*2).
Its worth bearing in mind that its the actuations of the hook that count, regardless whether it had load applied on it or not.
A lot of civilian clubs use golf buggies or ATVs (e.g. John Deere Gator) to tow a glider from where it lands back to the launch point; attaching the tow rope to one or other of the hooks. You can probably add 50% to the number of hook actuations* for these clubs. What the Air Cadets were doing for recoveries beyond hand push range before the 'pause' , I have no idea.
* If using the C of G or winch hook, it is possible to attach and release the hook by moving the back release ring rather than the release knob in the cockpit, however our regional examiner considers this to still be a hook actuation as far as its life is concerned.
