So why don't the instructers stop there and refine the techniques? Right now? Start getting these forms correct and 'deeper' instead of ploughing through the next 91 in a 'this will do' kinda style. That's what's happening at my class.
That's the way it works in TTCS. The instructors are under pressure to get the students to the end of the set in 3 months, and review for one month after that. In theory. This is so beginners' classes can start every 4 months.
Regarding refinement, the idea is that you get through the 108, then you go through the set again in continuing class, at about the same pace, but one level deeper. You get to the end, then go back to the start again, one level deeper. And so on. Different students might get more or less (or different) corrections,
to the best ability of the instructor.
Note the last phrase. Considering that the TTCS is promoting marginal students to beginner instructor status (yes, I still have contacts there), that instructor training weeks ("CIT week") are limited to a lot of practice (and speeches on "our charitable acts" and so on) for a vast number of people, those marginal students don't get to advance much. Also, the instructor training seems to be limited to the standardization of the set to a point where it becomes a mild calisthenic, not hurting anybody, but not giving the benefits that traditional Taijiquan instruction can offer.
... unless you're an indoor student such as DaPoets, whose personal instruction in Toronto seems to be very different from that available to most students, in and out of Toronto.
(DaPoet's assessment of the group may be accurate for the poor souls in the back row, but the rest are doing it at the level of most practitioners I've seen in my years in the TTCS.)
Kubrick, if you want a mild calisthenic, stick with TTCS. If you want the best it can offer, move to Toronto (or vicinity), practice a lot, volunteer a lot and become friends with the Administration. However, if you want good Taijiquan, go somewhere else. The TTCS has changed much due to its growth over the years -- the administration has become more focused on fundraising for the Cultivation Centre than anything else.
Just my opinion.
