No one seems to have observed that the AoA is instantaneous
whereas the ASI indicates what the aircraft was doing
moments ago.
I don't think this is true: all the ASI I've had or checked seemed to
respond in less than a second. Surely that's fast enough to keep up with
the glider? Just try blowing gently into a pitot and see how quick the
needle is. If takes "moments" to respond, you should check the indicator
and the pitot line.
The reason we are told to "fly attitude and don't chase the airspeed" is
it takes the glider a while settle down to a steady speed, not because
the ASI is slow.
