WBF, you keep asking for reference that speeds are being recalculated continuously when APP phase is active, yet you didn`t provide any reference that the contrary is true. In FCOM it`s only written that when app phase is activated, speeds are recalculated using current GW, not that they are memorized/freezed/whatever. As anyone actually flying A320 can check him/herself, speeds are being continuously updated after app phase activation as the GW reduces.
