Chun Li doesn't get knockdowns consistently if she doesn't have charge. If you can confirm fast enough and recognize the distance, she can end with Tenshokyaku instead of Lightning Kicks for a knockdown. Try to confirm into 5LK whenever possible, as it is her only light normal that combos into 236MK. 236MK is more consistent as an ender as it moves Chun Li forwards (as well as doing more damage).
