Those guidelines are designed to "bend" (not literally, of course!) all body types towards just one shape. Besides specificities of your own body that would require mixing different body type guidelines, there is also the question of if that ideal is how you want to look.
A famous example is Jennifer Lopez. She grew up in communities that saw voluptuous bodies and big rear ends as ideal for women. She says that in her early filming experiences, mainstream approaches that preach small behinds for women were confusing. People kept trying to find ways to hide or camoflouge the feature that she considered to be her best asset!
If you think your own legs are thin and gangly or short and stubby, then it doesn't matter what the "rules" say about whether you should make them look fuller or elongate them.
There are many ways to trick the eye described on this website and elsewhere. Start with the ones that are prescribed for the type that is closest to your own, but the goal is to bring out your uniqueness, in ways that please you. If following the "recipe" for your main type gives you a strange taste, then by all means take a glance at the other mixes and try a few of their ingredients to see if that works better for you.
