It depends on:
- How much "time served" (referred to as PFTPS, Previous Full Time Paid Service) you are creditted;
- are you doing a straight CT in the same MOC/MOSID; and
- what qualifications do you have that are valid in the Reg Force MOC you are entering.
PFTPS is calculated (IIRC) as your total days on eligible Class B (which was Class B over 90 days continuous when I did it) as "day for day" and 1/4 time for all other Res service time.
Example: You have 1000 days Reserve Service. 200 of those are eligible "day for day" Class B. 800 days are quarter time (Class B under 90 days continuous and Class A days). Your PFTPS should be 400 days. They should calculate your Reserve Service on your CF 10-07 form. I suggest you review it to make sure it is correct, as mine was missing lots of CL B time when I CTd.
