Greetings
Indeed the computed blended wind is not displayed to the crew, but the ground speed for ND display and MCDU predictions is the same one since the NEXT Waypoint is common.
Please note that 200 nm is for the pegasus/legacy HWL FMS/FMS2 whereas it is 100 nm on Thales/Smiths FMS2 despite what Airbus says.
because the FMP was developped by Smiths (B737)
