To the original poster:
Courses are only "capped" at their maximum course load (and sometimes a little above it) as laid out in the Training Plan, which is the course's master document. At WATC and on Western Area CITY courses they've long abandoned the "optimum course load" in the TP and maximum is the new optimum. I'm sure your area is the same. I've taught a couple BMQs over the max course load (one started with 51 candidates in 4 sections). In my opinion, running courses over the max load, especially platoon tactics courses like BIQ (BMQ and SQ are more about the section size than course size) is irresponsible. The only way BIQ will be "capped" at your training centre is that it will simply run large instead of huge.
Unfortunately the number of courses running is not sufficient for the current intake of recruits. This stems from: a) many recruits, b) few instructors. So some people are going to be left behind. About 50% of SQ-qualified recruits at my unit won't be getting their course this year unless something changes at the last minute. Which is a damned dirty shame. But the army is climbing out of a hole that took 10 years to dig. We have the money, we don't have the instructors.
For the record, I don't think its pampered and soft to want to be trained promptly. I'm not sure why your post has drawn such attacks. Just know that nobody is out to screw the troops here. Hard decisions are being made but there isn't a lot of choice.
I could do some of your homework and get WATC's reserve BIQ dates but the facts are that there will be no spots for out of area troops if all of 39 CBG gets only 30 spots (split between 4 units).
In the meantime, try to keep morale up amongst those soldiers not getting trained. The degree of bitterness they take from this experience will be reduced by good leadership and comradeship, and by good training at the unit.
