First, a random 2K block is generated. Then, 1 block is processed, 2 blocks are processed, 4 blocks are processed and so on. When the running time approaches the time limit, then the algorithm test stops. ?

That usually happens in UncheckedSetKey() for a block cipher. The keying time also includes the time to set the iv or counter if it is used. Some modes, like OCB, have non-trivial processing of the iv. Other modes, like CTR, encrypt the counter. If the processing does not occur, like with ECB mode, then it does not contribute to the time to key the cipher. But ECB mode still builds the round key table in UncheckedSetKey().
