Now I'm stepping out of my rhelm here, but CTs for ROTp and Pilot often take the priority because they have nofail deadlines (RMC must be full every year, no if ands or butts). After that it works on deadlines. When I was dealing with them 6 months ago, they had 5 brokers and were going down to 2 or something crazy like that.
There are many factors including, but not limited to
You rank (easier to get a PTE/CPL an Infmn spot than a Sgt)
Same trade to same trade (no course to load on)
Amount of time your PLAR Will take (if you are missing a reg force pirtion of a qual it has to get approved etc)
Strength of trade your going into
Priority trades
Many more factors I was never privy to, but they did tell me at one point, they had 5 people working on 4500 CTs. They are all great there and if your not getting a reply to an question, its cause there busy writing contracts. Its impossible, with so many factors, to give a timeline, but I have seen same trade CTs take 2-24 months and Cts different trades take 2-24 months.
And my spellcheck is not working. Sorry.
