A320 stall warning is not compensated for compressibility (unlike A330/350) I.e. it comes late at high altitude, well below Vsw. You’ll also have deterrent buffet well before that.

Hi!
in your example where 3.4 would be the corrected FPA. If you’d set 3.0, you will probably gain around 40ft/nm.

I think you’re missing the point here.
Indeed (ballpark)

However these are corrections...

When you enter an OFFSET and subsequently you fly in HDG, the flightplan will not automatically sequence, unless you pass the wpt within 5NM. Before arming NAV check your ‘TO-waypoint’.
