How is this done? On a purely theoretical basis, on observed behaviour, or a mix of the two?
For all up weight if the a/c climbs at say 1,000 feet per minute then we're probably happy, is there a stated minimum, I seem to recall someone mentioning 300 fpm for LAA permit?
For the CoG position is there a theoretical basis such as between 25% and 35% of the Mean Aerodynamic Chord (or whatever) or do the designers test at the airfield with varying loads until the test pilot says "That felt a bit squirrelly!!"?
