Also valid for your second question.
Why 2.5 deg lower than Flaps 3, and why would the alpha-max be only 0.5 deg above alpha-floor (14.5 deg) in the Flaps FULL case, instead of the apparent 2.5 deg margin with Flaps 3 (17.5 deg and 15 deg respectively)?
Good question, but it would be one for Toulouse.
My guess would be that, as CONF FULL is the normal configuration for landing, Airbus was not too excited to allow 17.5 deg of AoA that close from the ground with a higher risk for catastrophic tail strike ...
