I concur with the above response. It's not that one per year is cutting back, it's that any more than one was a temporary surge.
For a very long time it was 3 x CAPs per year, 2 x Ph3s, and 1 x Ph4.
The reason the extra courses were required in the last couple years is that French was cut out after SJ. What used to be a steady stream of 1-French-2-3-4 became all of a sudden the guys who graduated Ph1 last year (who have been on French) and guys who just graduated Ph1 last week all coming to Gagetown at the same time.
So what you had was a hose that was used to a steady stream of water, and then this football-like bulge of extra candidates coming through, and in order to accommodate that extra courses were ran.
Now, the system has caught up from the French being eliminated part, and it's back to a steady stream of only one SJ serial at a time showing up here.
If you are lucky enough to pull off a fall CAP, winter Ph3, and summer Ph4 then you’re fine. But say for example you get injured or just show up in the winter so your Ph3 (DP 1.1) is in the summer, you would then do what everyone used to do and go do On the Job Training (OJT) somewhere for 8 months as a sort-of-qualified helper before returning to Gagetown for Ph4.
Whatever you do should that be the case, beg and plead your way out of Personnel Awaiting Training (PAT) Platoon so you can get some real-world experience.
