    Alex,
    
    My guess would be observational proficiency.  It took me about two
    years to achieve proficiency in altitude shots with the artificial
    horizon; I quickly got within 0.5' of arc, but getting well under
    0.2' took much longer.  You seem to be pretty close.  Perhaps Frank
    could comment on how long it took him.
