Yeah, cycles used by code isn't integer divisible by cycles available in one frame. There is also CIA access which is not slowed down by DMA and is not in sync with DMA cycles.

Only cycle-exact mode emulates DMA stealing cycles from CPU. This is not normally a problem because almost all programs use copper which is accurate in all modes.
