It isn't easy to give specific numbers from memory. However, it is true that initially a relatively limited amount of stock footage was shot. They were based on a catalog of similar assets from TOS. The exact number of 30 mentioned here can't be that far-fetched. That was simply the result of the fact that the first 6-foot model was too big and unwieldy and the 2-foot model was too small and undetailed for closer shots. In consequence, the first two seasons show a very limited variation of model shots - very noticeable. That's why the 4-foot model was introduced in season 3, which was a compromise between the level of detail and handling. From then on, the use became more flexible and frequent. The original set of stock assets was supplemented by the 4-foot model with specific requirements for the episodes but also these shots were reused many times. Nevertheless, in all 7 seasons, you will find the same initial stock shots again and again set in a different environment, mirrored, scaled, etc.
Apropos stock footage... how many times has the footage of the exploding Bird of Prey been reused? 3 times in the movies and once in DS9, right? LOL
