If you want the maths then each member of a UK CG SAR unit does roughly 200-250 flying hours a year (taskings and training). Because of the working time directive they can only work an average of 8 shifts per month (max duty hours 2000).
So on average a UK CG SAR pilot will achieve 2.1 to 2.6 flying hours per shift.
The number of training hours available hasn't changed with the new contracts (which were effectively decided by the military) so I assume the CG and the MOD are happy with maintaining that level of currency. Of course with harmonization the big question is will the number of training hours available be the same across the board for both civil and military pilots.
