SPECULATION: During flight testing Airbus discovered the possibility to certify a lower speed and grabbed the chance as the whole idea behind landing is to stop the aircraft. Whether or not the possibility was there already on the sharkletted CEO's but such testing was not done or not explored for commonality purpouses is a speculation squared.
A nice find. The Vmca is higher on the -271N, green dot as well if only by a little.
F and S remain identical, while Vls CF3 is higher by 2 kts, that is somewhat perplexing.
Nice catch, I am checking CFM/CFM LEAP data and the VMCA is 4 kts higher on the latter. Other than that, I only find a significant difference on Vref between CEO/NEO as discussed above, ie. 6 kts lower on the NEO, but that is due to the higher flap angle.
