How interesting that this months "Sport Aerobatics" had 2 good articles that ...Directly{Giles Henderson} & indirectly{yours Wes Liu} addresses this very topic.
Also Giles's article educates as to the metric that use to be used to establish each planes "API" or aerobatic performance index. He also did a good job of pointing out that 2 planes with big differing API's could compete in the same category by giving the lower performance plane access to it's potential energy by designing sequences that didn't favor the higher performance planes.....Just extrapolate his point from the entry of the sport to advanced.
And to the point of designing sequences that do this...I made a post on this forum addressing the subject last year{fair unknowns} in October when the new knowns for 14 were being considered.
